安全最佳实践
**WIF 处理:**提供钱包导入格式 (WIF) 密钥时务必格外谨慎。确保 MCP 服务器运行环境和通信通道安全可靠。建议在本地或受信任的网络中运行服务器。避免在没有可靠身份验证和传输安全(HTTPS)的情况下公开服务器。
如果使用基于文件的方法,则安全地存储钱包文件(尽管当前 API 似乎基于 WIF)。
对所有状态改变操作(转移、合约调用)使用
confirm: true以确保交易由网络处理。使用强密码安全地存储钱包文件

Available Tools
19 toolsestimate_invoke_feesC
Estimate network and system fees for a contract invocation by script hash or a generic contract reference.
| Name | Required | Description | Default |
|---|---|---|---|
| args | No | Optional: Method arguments | |
| network | No | Optional: Network | |
| contract | No | Generic contract reference: known name, script hash, or Neo address | |
| operation | Yes | Method name | |
| nameOrHash | No | Backward-compatible alias for contract name or script hash | |
| scriptHash | No | Contract script hash | |
| contractName | No | Exact contract name resolved through N3Index or a live manifest | |
| signerAddress | Yes | Signer address |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must fully disclose behavior. It only states 'estimate fees' without explaining what this entails (e.g., simulation, return format, side effects). Minimal behavioral context is provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence is concise but overly brief. It conveys the core function without waste, but lacks structure or front-loading of critical details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, yet description omits return value clues. With 8 parameters, it fails to guide which to use for different scenarios (e.g., contract vs nameOrHash vs scriptHash). Incomplete for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage, so parameters are documented. The description adds 'by script hash or generic contract reference' which aligns with multiple parameter options, but does not clarify relationships or preferred usage among them.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool estimates network and system fees for contract invocations, specifying that it can use a script hash or generic contract reference. However, it does not explicitly distinguish from the sibling 'estimate_transfer_fees' tool, which is inferred but not stated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. The name suggests contract invocation fee estimation, but no conditions, prerequisites, or exclusions are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
estimate_transfer_feesB
Estimate network and system fees for a transfer.
| Name | Required | Description | Default |
|---|---|---|---|
| asset | Yes | Asset hash | |
| amount | Yes | Amount | |
| network | No | Optional: Network | |
| toAddress | Yes | Recipient address | |
| fromAddress | Yes | Sender address |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description does not disclose behavioral traits (e.g., idempotency, side effects, permissions). Fails to add value beyond the basic purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded, and concise with no unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Lacks description of return values (no output schema), which is essential for an estimation tool. Could mention that it does not execute a transfer.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage; description adds no extra meaning to parameters beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool estimates network and system fees for a transfer, distinguishing it from sibling `estimate_invoke_fees` which estimates invocation fees.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage for fee estimation before transfers but no explicit guidance on when to use this versus alternatives like `estimate_invoke_fees` or `transfer_assets`.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_application_logA
Get the application log for a transaction hash.
| Name | Required | Description | Default |
|---|---|---|---|
| txid | Yes | Transaction hash (64 hex chars, optional 0x prefix) | |
| network | No | Optional: Network |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, side effects, or required permissions. The description's single sentence does not compensate for the lack of transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with no wasted words. It is appropriately sized for the simple functionality.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple log retrieval tool with no output schema, the description is minimal but adequate. However, it does not hint at the log content or return format, which could be useful for agents.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage with descriptions for both parameters ('txid' and 'network'). The description adds no additional meaning beyond what the schema provides, meeting baseline expectations.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get the application log for a transaction hash.' It uses a specific verb and resource, and distinguishes from sibling tools like 'get_transaction' which returns different data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving logs for a transaction but provides no explicit guidance on when to use this tool versus alternatives or any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_balanceA
Get NEO, GAS, and NEP-17 balances for an address.
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Neo N3 address | |
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must cover behavioral traits. It only states the output type (balances) but omits details like error handling, rate limits, or authentication requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence conveys the entire purpose efficiently with no wasted words. It is front-loaded and easy to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple and the description covers the essential purpose. However, without an output schema, the return format is undefined, and the description does not elaborate on the structure of the balances. Adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds value by listing specific token types (NEO, GAS, NEP-17), which is not in the schema. The schema already fully describes parameters, so baseline is 3; the extra detail raises it to 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it gets NEO, GAS, and NEP-17 balances for a given address. The verb 'get' and resource 'balances' are specific, and it distinguishes from sibling tools like get_nep11_balances.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as get_nep17_transfers or get_nep11_balances. The description lacks any contextual cues for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_blockC
Get block details by height or hash.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Optional: Network | |
| hashOrHeight | Yes | Block hash (64 hex chars) or block height (number) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It does not disclose behavioral traits like error handling for invalid hash/height, network fallback behavior, or size limits. The verb 'Get' implies read-only, but more is needed for transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence that front-loads the purpose. While very short, it contains no filler. However, it could be considered under-specified rather than concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description should mention what the returned 'block details' include (e.g., all fields, transactions). The absence makes it somewhat incomplete for an AI agent to fully understand the output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description adds no new meaning beyond the schema's parameter descriptions, which already explain the hash/height distinction and optional network parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Get' and the resource 'block details', and specifies the lookup method 'by height or hash'. This distinguishes it from siblings like get_blockchain_info or get_block_count, though it doesn't detail what 'details' includes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as get_transaction or get_block_count. The description lacks context for when one might prefer this over siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_blockchain_infoA
Get blockchain height, validator info, and the active network.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must carry the burden. It mentions returned info but does not explicitly state it is read-only or discuss any side effects, though 'Get' implies a safe read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
One concise sentence that front-loads the purpose with no redundant or extraneous information. Every word contributes value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lists the specific pieces of information returned, compensating for the lack of output schema. It does not mention the optionality of the network parameter, but overall it is sufficient for a simple tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a description for the single parameter. The tool description adds no additional meaning beyond what the schema already provides, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Get' and the specific resources: blockchain height, validator info, and active network. It is distinct from sibling tools like get_balance or get_block.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit when-to-use or when-not-to-use guidance. However, the purpose implies use for overall blockchain state, but no comparison to siblings like get_network_mode or get_block_count.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_block_countB
Get the block count and latest block height for the selected network.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It only states the tool retrieves data but fails to mention side effects, permissions, rate limits, or response structure. The lack of any safety or mutation context is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, front-loaded sentence that wastes no words. Every part is essential, and the structure is optimally concise for quick parsing.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (1 parameter, no output schema), the description adequately conveys the return value (block count and height). Minor ambiguity around 'block count' (whether it is total or something else) prevents a perfect score, but it is otherwise complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and fully describes the 'network' parameter (mainnet or testnet). The description adds no additional meaning beyond 'selected network', so it meets the baseline of 3 without improvement.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the tool returns 'block count and latest block height' for the selected network, clearly distinguishing it from siblings like 'get_block' (returns a specific block) and 'get_blockchain_info' (returns broader chain info). Verb 'Get' plus resource 'block count and height' is specific and unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as 'get_block' or 'get_blockchain_info'. The description does not specify context or prerequisites, leaving the agent to infer usage from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_contract_infoC
Get metadata and operations for a contract by known name, script hash, or Neo address.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Network to use: "mainnet" or "testnet" | |
| contract | No | Generic contract reference: known name, script hash, or Neo address | |
| nameOrHash | No | Backward-compatible alias for contract name or script hash | |
| contractName | No | Supported contract name |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description does not disclose that it is a read-only operation, does not mention rate limits, authentication, or what 'operations' means. Minimal behavioral context beyond basic purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no wasted words. However, could include more useful details without being verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, no annotations, and description does not explain what 'metadata and operations' entails or the response format. Four optional parameters with no required ones may confuse an AI agent on what to provide.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% description coverage, but the description merely restates the identification methods without clarifying the redundancy or relationship between the three similar parameters (contract, contractName, nameOrHash). Adds no meaningful information beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the verb 'Get' and the resource 'metadata and operations for a contract', and specifies three identification methods (name, script hash, Neo address). This distinguishes it from sibling tools like get_contract_status or deploy_contract.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives such as get_contract_status, get_application_log, or list_famous_contracts. Does not mention prerequisites or when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_contract_statusB
Check whether a contract is deployed and inspect its current on-chain status by known name, script hash, or Neo address.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Network to use: "mainnet" or "testnet" | |
| contract | No | Generic contract reference: known name, script hash, or Neo address | |
| nameOrHash | No | Backward-compatible alias for contract name or script hash | |
| contractName | No | Supported contract name |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only states it checks deployment and status, but no mention of side effects, read-only nature, or response behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence front-loading purpose. No redundant words or information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple look-up tool, but no output schema or description of what 'inspect status' returns. Sibling tools exist but no hints.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so schema already describes parameters. Description does not add extra meaning beyond what's in the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool checks contract deployment and status by name, script hash, or address. Verb and resource are specific, and it distinguishes from siblings like get_contract_info by mentioning the lookup methods, though not explicitly.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs siblings (e.g., get_contract_info). No mention of when not to use it or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_nep11_balancesB
Get NEP-11 balances for an address.
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Neo N3 address | |
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must convey behavioral traits. It does not mention rate limits, authentication, output format, or any side effects. The brief sentence 'Get NEP-11 balances for an address' provides minimal transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, front-loaded, and contains no extraneous information. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with 2 parameters and no output schema, the description is minimally complete but lacks details on return type, error handling, or example usage. It could mention that balances are returned as a list of token data.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the description adds no additional meaning beyond the schema descriptions. It does not elaborate on the parameters (e.g., address format, network enumeration). Baseline 3 is appropriate given full schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool fetches NEP-11 balances for an address, using a specific verb and resource. It distinguishes from sibling tools like get_balance (NEP-17) and get_nep11_transfers (transfers vs balances).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, no prerequisites, exclusions, or context provided. The description only says what it does without any usage direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_nep11_transfersC
Get NEP-11 transfer history for an address.
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Neo N3 address | |
| network | No | Network to use: "mainnet" or "testnet" | |
| toTimestampMs | No | Optional end timestamp in Unix epoch milliseconds | |
| fromTimestampMs | No | Optional start timestamp in Unix epoch milliseconds |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must disclose behavioral traits. It only states a read operation ('Get'), but fails to mention pagination, rate limits, response size, or error conditions. This is insufficient for an agent to anticipate side effects or constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that front-loads the purpose. It wastes no words, though it could be more informative without sacrificing brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of annotations and output schema, the description should elaborate on return format, pagination, and edge cases (e.g., empty history). It only states the basic function, leaving significant gaps for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so each parameter already has a description in the schema. The tool description adds no extra meaning or context for parameters beyond 'transfer history'. Baseline 3 is appropriate as no additional value is provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves NEP-11 transfer history for an address. The verb 'Get' and resource 'NEP-11 transfer history' are specific. However, it does not explicitly differentiate from the sibling tool get_nep17_transfers, although the token standard is distinct in the name.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like get_nep17_transfers or get_nep11_balances. The description lacks context on prerequisites, typical use cases, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_nep17_transfersB
Get NEP-17 transfer history for an address.
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Neo N3 address | |
| network | No | Network to use: "mainnet" or "testnet" | |
| toTimestampMs | No | Optional end timestamp in Unix epoch milliseconds | |
| fromTimestampMs | No | Optional start timestamp in Unix epoch milliseconds |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose any behavioral traits such as pagination, rate limits, data freshness, or authentication requirements. It merely restates the purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence. While it lacks detail, it is efficient and front-loaded with the key purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no output schema, yet the description does not hint at the return format or structure of transfer history. For a query tool, this incomplete context hampers effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, so each parameter is documented. The description adds no additional meaning beyond the schema, resulting in a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves NEP-17 transfer history for an address, using a specific verb and resource. It distinguishes from siblings like get_nep11_transfers (different token standard) and get_balance (just balance).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like get_nep11_transfers. The context is implied from the name and schema, but no direct comparison or exclusion criteria are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_network_modeA
Get the active network mode and available Neo networks.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description does not disclose any behavioral traits beyond the basic read operation. No annotations are provided, so the description carries the full burden. It does not mention authentication, rate limits, or whether the list of networks is complete or filtered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence that efficiently conveys the tool's purpose. No superfluous words or unnecessary details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is simple and the description covers the basics, it lacks details on the return format. Given the absence of an output schema, the description should ideally hint at the structure of the response (e.g., JSON fields) to help the agent parse results. Also, no contextual info on prerequisites or side effects.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has no parameters, so the input schema covers 100% of the interface. The description adds value by specifying that it returns both the active mode and the available networks, which is meaningful context beyond the empty schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool retrieves the active network mode and available Neo networks. Verb 'Get' and resource 'network mode' and 'Neo networks' are specific and unambiguous. It distinguishes from sibling 'set_network_mode'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. However, the purpose implies it is for reading network mode, and the sibling 'set_network_mode' handles writing, which provides indirect context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_transactionB
Get transaction details by hash.
| Name | Required | Description | Default |
|---|---|---|---|
| txid | Yes | Transaction hash (64 hex chars, optional 0x prefix) | |
| network | No | Optional: Network |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, and the description does not disclose behavioral traits like idempotency, error handling (e.g., missing transaction), or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise with one front-loaded sentence, but lacks structure for complex information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, so description should elaborate on return details or network optionality. Currently minimal for a tool with two parameters and many siblings.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with clear parameter descriptions. The description adds no additional value beyond restating 'by hash'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool retrieves transaction details using a hash, distinguishing it from sibling tools like get_block or get_balance.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidance provided. Lacks context on when to use this tool over alternatives, such as get_block for block-level queries or get_balance for account data.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_unclaimed_gasB
Get the amount of GAS claimable by an address.
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Neo N3 address | |
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits, but it only states 'get the amount' without clarifying that it is a read-only operation with no side effects, authentication needs, or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no wasted words, though it could be slightly more informative without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description fails to mention return format, whether the operation is read-only, or any other contextual information needed for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the description adds no additional meaning beyond what the schema provides; baseline score applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves the amount of GAS claimable by an address, distinguishing it from the sibling tool 'claim_gas' which would perform the claim action.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'claim_gas', nor are there any prerequisites or exclusion criteria mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_walletA
Get sanitized metadata for a locally stored wallet by address.
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Neo N3 address |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral traits. It mentions 'sanitized metadata' but does not disclose side effects, error conditions, or permissions. This is minimal for a read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is front-loaded with the verb and resource. It is concise without any redundant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema, the description adequately covers input and output. However, it could explicitly mention what 'locally stored' means or handle missing wallet cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the schema already describes the parameter (address). The description adds 'locally stored wallet' context but does not enhance understanding beyond the schema's own description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (Get), the resource (sanitized metadata for a locally stored wallet), and the parameter (by address). It effectively distinguishes from sibling tools like create_wallet or import_wallet.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide explicit when-to-use or when-not-to-use guidance. While it implies use for retrieving wallet metadata, it lacks alternatives or exclusions compared to siblings like import_wallet.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
invoke_contractB
Run a read-only smart contract invocation without signing or broadcasting a transaction.
| Name | Required | Description | Default |
|---|---|---|---|
| args | No | Method arguments as an array of values | |
| network | No | Network to query | |
| contract | No | Contract reference: script hash, Neo address, exact N3Index name, or a previously discovered manifest name | |
| operation | Yes | Contract method name to invoke | |
| nameOrHash | No | Contract name or script hash (alias for contract) | |
| scriptHash | No | Contract script hash (40 hex chars, optional 0x prefix) | |
| contractName | No | Exact contract name resolved through N3Index or a live manifest |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states it is read-only and non-broadcasting, clarifying it is non-destructive. However, with no annotations provided, it fails to disclose other behavioral aspects like error handling, result structure, or limits. The read-only trait is the key behavioral detail, earning a 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single concise sentence conveys the core purpose with no redundancy. However, it could be slightly more structured (e.g., separate lines for key details) without losing brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of 7 parameters and no output schema, the description is too minimal. It does not explain how to use multiple contract identifiers, expected output format, or error conditions. For a tool of this complexity, more context is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the descriptions in the schema already document all parameters. The tool description adds no extra meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: performing a read-only contract invocation without signing or broadcasting. This precisely distinguishes it from other tools like estimate_invoke_fees or get_contract_info.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, nor does it explain which parameter among the multiple contract identifiers (contract, nameOrHash, scriptHash, contractName) should be used in different scenarios. Required parameter 'operation' is mentioned in schema but not in description context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
list_famous_contractsB
List supported well-known contracts for the selected network.
| Name | Required | Description | Default |
|---|---|---|---|
| network | No | Network to use: "mainnet" or "testnet" |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description does not disclose behavioral traits like auth requirements or data freshness. Only states basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, efficient and to the point with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Description is minimal. Does not explain what 'famous contracts' are or if the list is dynamic. Agent may lack full context for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers the parameter with description of allowed values. Description adds no new semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. No context on prerequisites or network availability.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
wait_for_transactionC
Wait for a transaction to be confirmed on-chain.
| Name | Required | Description | Default |
|---|---|---|---|
| txid | Yes | Transaction hash (64 hex chars, optional 0x prefix) | |
| network | No | Optional: Network | |
| timeoutMs | No | Optional timeout in milliseconds | |
| pollIntervalMs | No | Optional polling interval in milliseconds | |
| includeApplicationLog | No | Include the application log once the transaction confirms |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It fails to disclose polling behavior, timeout consequences, or side effects. The fact that it waits is implied but not detailed (e.g., does it block until confirmed or return immediately?).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with no wasted words. However, given the lack of annotations, the description is too short to convey necessary behavioral information; conciseness could be improved with more context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, 5 parameters, and no annotations. The description does not explain return value, error conditions, or how parameters like timeoutMs affect behavior, leaving the agent with significant gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% description coverage for parameters, so description adds no additional meaning. Baseline score of 3 is appropriate since the schema already explains each parameter's purpose.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool waits for a transaction to be confirmed, using specific verb and resource. However, it does not differentiate from siblings like get_transaction which could also check confirmation status.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., get_transaction for one-time check). The description lacks context about prerequisite conditions or post-conditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Scored across 19 tools
Most tools target distinct resources, but get_balance and get_nep17_balances overlap since get_balance already includes NEP-17 balances. get_blockchain_info and get_network_mode also share active-network information, and get_contract_info vs get_contract_status could be confused without careful reading.
The naming is mostly consistent with clear get_* prefixes and snake_case verbs. Minor deviations exist with list_famous_contracts, wait_for_transaction, invoke_contract, and estimates, but they are still predictable and readable.
At 19 tools, the server sits in the heavier range and feels borderline for a focused toolkit. Each tool is individually reasonable, but the set could be tightened by consolidating overlapping query tools.
The server covers a solid range of read-only Neo N3 operations: balances, transfers, blocks, transactions, contracts, fees, and network info. However, there are notable gaps for a full blockchain MCP surface, such as sending transfers, claiming GAS, or performing signed contract invocations.
