Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.0
Disambiguation5/5
Every tool has a clearly distinct purpose, with no overlapping functionality. Tools like get_price, get_exchange_ticker, compare_prices, and get_consolidated_orderbook are all price-related but target different sources and granularities, clearly differentiated by descriptions.
Naming Consistency5/5
All tools follow a consistent verb_noun snake_case pattern (e.g., get_price, list_top_coins, compare_funding_rates). The naming is predictable and makes it easy to infer tool purpose from the name alone.
Tool Count2/5
With 49 tools, the server is significantly over the typical well-scoped range of 3-15. While each tool appears justified, the sheer number makes it overwhelming for an agent to efficiently select the right tool, increasing cognitive load.
Completeness4/5
The tool set covers an extensive range of crypto data: prices, market data, exchanges, DEX, DeFi, NFTs, stablecoins, funding rates, and more. Minor gaps exist (e.g., no direct historical price series for multiple coins simultaneously), but overall the surface is comprehensive for the domain.
Average 4.5/5 across 49 of 49 tools scored. Lowest: 3.7/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It only states 'List' (implying read-only) but omits details on caching, rate limits, data freshness, or any side effects, leaving gaps for an AI agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with a short introductory sentence and clear bullet-like parameter and return listings. No extraneous information, though structure could be slightly improved with formatting.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple list tool with pagination, the description covers parameters and explicitly lists return fields (compensating for lack of output schema). It lacks error handling details but is complete enough for typical usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add meaning. It provides brief explanations for each parameter (e.g., 'Sort order' for order, '1..250 per page' for per_page), adding some value beyond the schema defaults and enums, but not deeply elaborating.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it lists derivatives exchanges (futures/perp/options) ranked by open interest or volume, using a specific verb and resource. It distinguishes itself from sibling tools like list_exchanges_directory by focusing on derivatives.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says 'Use to compare derivatives venues... by size,' providing a clear use case. However, it does not mention when not to use it or alternative tools, which would improve guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries the full burden. It discloses that the tool is a read-only list operation and details the return fields (e.g., id, name, market_cap). However, it does not mention any side effects, rate limits, or authentication requirements, which is acceptable for a simple list tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections for args and returns, and it is front-loaded with the main purpose. It is concise, though the code block for args and returns adds slight verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has one optional parameter and no output schema, the description adequately covers the input, output, and use case. It explicitly lists return fields, which is sufficient for an agent to understand the tool's behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter is 'order' with an enum of sort orders. The description notes 'order: Sort order,' which adds minimal meaning beyond the schema's 'title' and enum values. The schema coverage is 0% for property descriptions, so the description should compensate more here.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'List all coin categories with aggregated market data (market cap, 24h volume, 24h change).' It specifies the verb (list), resource (coin categories), and differentiates from siblings by explicitly mentioning the use case of finding category IDs for list_top_coins.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage: 'Use to discover narratives... and to find category IDs you can pass to list_top_coins(category=...).' This gives clear context for when to use the tool, though it does not mention when not to use it or provide direct alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description explains the funding rate concept and notes that return fields vary by exchange, adding some transparency. However, without annotations, it fails to disclose rate limits, authentication requirements, or potential side effects (though the tool is clearly read-only). The behavioral disclosure is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a brief summary, explanatory context, and explicit Args/Returns sections. It is front-loaded and contains no filler, though the funding rate explanation could be slightly condensed. Overall efficient and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite lacking an output schema, the description lists return fields and notes variability. The two required parameters are fully described with examples. The tool is relatively simple, and the description provides sufficient context for correct invocation, though missing potential error handling or usage constraints.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description compensates for the schema's 0% coverage by providing concrete examples for exchange_id ('binance', 'okx', 'bybit', 'bitmex') and symbol ('BTC/USDT:USDT', 'BTC/USD:BTC'), adding meaning beyond the bare string type. This guides the agent effectively on parameter values.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description starts with a clear verb+resource phrase 'Get the current funding rate for a perpetual-futures contract on a specific exchange,' which immediately distinguishes it from sibling tools like get_funding_rate_history (historical) and compare_funding_rates (comparison). The context about funding rate further clarifies the tool's domain.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for current rate but does not explicitly state when to use alternatives like get_funding_rate_history for historical data or compare_funding_rates for cross-exchange comparison. No exclusions or prerequisites are mentioned, leaving the agent to infer usage boundaries.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It mentions it's a snapshot (not a stream), but does not explicitly state it's a read-only operation, any authentication requirements, rate limits, or side effects. This 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured: a brief summary, usage note, parameter documentation, and return format. Every sentence adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
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 covers the return structure, parameter details, and purpose. It lacks error handling or edge-case behavior, but is otherwise comprehensive for a snapshot tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description adds essential context for all three parameters: explains exchange_id as CCXT ID, symbol with example, and limit with default and behavior across exchanges. This fully compensates for the schema's lack of descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
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 'Level-2 order-book snapshot', specifies it's from a specific exchange, and lists use cases. It distinguishes from sibling 'get_consolidated_orderbook' by clarifying it's per exchange.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives usage context ('assess liquidity, spread, short-term supply/demand') and notes it's a snapshot, not a stream. However, it does not provide explicit when-not-to-use guidance or compare to alternatives like get_consolidated_orderbook.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are provided, the description carries the full burden. It states that it is a listing operation returning an array of NFT collections with specific fields. However, it does not disclose rate limits, authentication needs, or error handling, which would be helpful.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise with a clear purpose sentence, followed by structured Args and Returns sections. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a listing tool with 3 parameters and no output schema, the description provides acceptable information: sort options, pagination, and return fields. It directs to 'get_nft_collection' for details. Could be improved by noting default sort direction.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The descriptions of parameters are minimal ('Sort order', '1..250', 'Page number'), but the purpose text adds meaning by listing sortable metrics. Schema coverage is 0%, so the description partially compensates but does not explain all enum values.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists NFT collections with sort options (floor price, market cap, 24h volume). It distinguishes from sibling 'get_nft_collection' which is for a single collection.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains the sort, pagination, and return fields. It directs to 'get_nft_collection' for details, providing an alternative. However, it does not explicitly state when not to use this tool or compare to other listing tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description partially discloses behavior: it mentions the return format and that limit has a maximum of ~1000 depending on venue. However, it omits other behavioral traits like rate limits, data freshness, authentication requirements, or idempotency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is organized into a brief intro, usage line, Args section, and Returns. It is concise without being terse, though the structure could be slightly more streamlined.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description includes a Returns section detailing the array of trade fields. It also covers all parameters adequately. Missing context like authentication or rate limits, but overall complete for a public data retrieval tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description compensates well by providing an Args section that explains each parameter (exchange_id, symbol, limit) with examples and constraints (e.g., default 50, max ~1000). Adds meaning beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Get recent public trades (the tape) for a symbol on a specific exchange.' It uses a specific verb-resource pair and outlines use cases (inspect order flow, identify large prints, compute metrics), distinguishing it from other get_* siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description explicitly says 'Use to inspect order flow, identify large prints, or compute very short-term trade-driven metrics.' This gives clear guidance on when to use, but lacks explicit when-not-to-use or differentiation from other similar tools in the sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. While it mentions 'real-time' and the return fields, it lacks disclosure of behavioral traits such as rate limits, data source reliability, authentication requirements, or what happens if the exchange is unavailable. This is insufficient for an unannotated tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: a single-sentence purpose, followed by a usage guideline, then parameter details, and a returns list. Every sentence provides essential information with no redundancy or filler. Well-structured and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool simplicity (2 parameters, no output schema), the description is complete: purpose, usage, parameter semantics, and return fields are all covered. The return fields list compensates for the lack of output schema, and the context signals indicate no nested objects or enums, so no additional explanation is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description adds crucial semantic information for both parameters: 'exchange_id' is explained as a CCXT ID with an example, and 'symbol' is described as a CCXT unified symbol with multiple examples including linear perpetual formats. This far exceeds the minimal schema titles.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'get', the resource 'real-time ticker', and specifies the scope 'one symbol on one exchange'. It distinguishes from siblings by mentioning 'specific venue' and giving examples like 'BTC on Coinbase', which helps the agent select this tool over aggregated or multi-exchange alternatives.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly provides usage context: 'Use when the user asks about price on a specific venue' and includes examples. However, it does not explicitly mention when not to use the tool or list alternative siblings, though the guidance is clear and sufficient for most cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that the tool returns an object with specific fields, implying a read-only operation. However, it does not mention data freshness, authentication requirements, or any potential rate limits, leaving gaps in behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is mostly concise, with two paragraphs: purpose and return fields, then usage guidelines. It includes a separate 'Returns:' section that repeats some information, which is slightly redundant but enhances clarity. Overall, it is well-structured and informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters, no output schema, and no annotations, the description covers the tool's purpose, return data, and usage context sufficiently. It distinguishes from siblings and lists all return fields, making it nearly complete for its simple nature.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters (100% coverage), so no parameter description is needed. The description adds value by listing return fields, which compensates for the lack of an output schema. Baseline for 0 params is 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves global DeFi market stats, listing specific data points like total market cap, DeFi-to-Eth ratio, and top coin by share. The verb 'Get' and resource 'global DeFi market stats' are explicit, and it distinguishes from sibling tools by referencing alternatives for granular data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit when-to-use guidance and names alternative tools (get_protocol_tvl and list_chains_tvl) for more granular protocol or chain-level breakdowns, helping an agent decide when not to use this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description discloses fallback behavior to fetch_open_interest_history, explains the return object format, and mentions error handling for unsupported exchanges. This adds significant behavioral context beyond just the tool name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: definition, interpretive guideline, fallback note, parameter docs, return description. It is slightly long but each sentence adds value, and the structure is logical.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description covers return fields, fallback, and error handling. It is complete enough for an agent to invoke correctly without additional context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description explains each parameter: exchange_id as 'CCXT exchange ID supporting perps' and symbol with example suffix. It also details the return object structure, compensating for the lack of schema details.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description starts with a clear verb+resource: 'Get the current open interest (OI) for a perpetual contract on one exchange.' It distinguishes itself from sibling tools like get_funding_rate and get_funding_rate_history by explicitly mentioning them as alternatives for funding-rate context.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides interpretive guidance on reading OI with price action and explicitly names alternative tools for funding-rate context. It lacks explicit when-not-to-use guidance but the context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Given no annotations, the description discloses the API key dependency, potential error without key, and return structure (object with arrays). It is transparent about behavior but could mention read-only nature explicitly.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is reasonably concise, with a clear first sentence, separate sections for args and returns. It could be slightly more streamlined but remains efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
In the absence of annotations and output schema, the description covers purpose, authentication, fallback, return structure, and parameter semantics. It does not explicitly state default values or optionality, but overall provides adequate context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The 'Args' section explains each parameter's purpose and includes enum values for 'top_coins' but not for 'duration'. Schema coverage is 0%, so description adds meaning, but not all enum options are listed, leaving some gaps.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets the biggest price movers (gainers and losers) over a time window, with a specific verb and resource. It distinguishes itself from sibling tool 'list_top_coins' by mentioning a fallback, showing differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly notes the API key requirement and fallback to 'list_top_coins' if no key is provided, giving clear when-to-use and when-not-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses that data is search-driven and returns a specific structure with price snapshots. No annotations exist, so description carries full burden. It does not mention potential limits like the number of items returned or any rate-limiting behavior, which would be helpful.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise and well-structured: first sentence states purpose, second provides usage context, then a clear 'Returns' section with specific fields. No unnecessary words; every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and no output schema, the description fully explains what the tool returns and the context for use. It includes enough detail for an agent to understand the output and decide when to invoke it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0 parameters, the schema provides no information. The description adds meaning by detailing the return structure (coins, nfts, categories) and fields like item.id, item.name, etc. This exceeds the baseline of 3 for high schema coverage and effectively compensates for the lack of params.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets trending coins, NFT collections, and categories based on last 24h searches. It distinguishes itself from siblings like get_top_gainers_losers by emphasizing search-driven vs volume-driven, and specifies the exact data returned.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly gives example questions ('what is the market paying attention to right now?') and explains the search-driven nature, helping the agent decide when to use it. However, it does not explicitly mention when not to use it or point to alternative tools for volume-driven queries.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully covers behavioral aspects: it explains that boosts are paid promotions, that high spend does not imply quality/traction/safety, and that it signals active pushing. It also documents return structure including error responses. A slight deduction for not mentioning rate limits or other potential constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a brief statement, a caution section, usage alternatives, and parameter/return doc. It is front-loaded with the core purpose. Some redundancy in the caution section could be trimmed, but overall efficient for the content delivered.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema, the description compensates by listing return fields (chainId, tokenAddress, etc.) and error handling. It also provides contextual advice about using complementary tools for deeper analysis. However, it could mention the ranking criterion or refresh frequency, leaving some minor gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, so the description must compensate for the single parameter 'limit'. It states 'Max tokens to return', which is functional but minimal. No range, default behavior beyond schema, or caveats are provided, giving only basic value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists currently top-boosted tokens on DexScreener, a paid promotion. It explicitly distinguishes itself from siblings like list_latest_dex_tokens and get_dex_token_pairs, providing a specific verb and resource with context.

This goes well beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List' and resource 'trading pairs (markets) supported by a specific exchange.' It distinguishes from siblings like get_exchange_info (exchange metadata) and get_exchange_ticker (ticker prices) by focusing on market list discovery.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage context: 'Use to discover what symbols an exchange trades... or to enumerate available perpetual contracts.' It also references list_supported_exchanges for valid exchange IDs. However, it does not explicitly state when not to use this tool or compare to alternatives like get_exchange_ticker.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It describes the return structure and notes that coin IDs are not ticker symbols. It does not mention rate limits, pagination, or error behavior, but provides sufficient behavioral clarity for a simple lookup tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with a clear purpose, usage note, parameter list, and return description. Slightly verbose but each sentence adds value; front-loaded with key information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit usage scenarios are given (e.g., 'best stablecoin yields', 'highest APY on Aave'), and an alternative tool is mentioned for protocol-level TVL, guiding when to use this vs. siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It details return structure (arrays for coins, exchanges, categories, nfts) and purpose. However, it omits information about rate limits, authentication, or any side effects. Since it's a search tool, likely read-only, but additional behavioral notes would be beneficial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is concise and well-structured: a brief purpose statement, explicit usage guidance, then structured Args and Returns sections. Every sentence adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite no output schema, description fully explains return structure with example fields. Covers all necessary aspects for a search tool: what it searches, how to use, and expected output, making it complete for its complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Single parameter 'query' has no description in input schema. Description adds examples ('btc', 'uniswap', 'bored ape') and clarifies it's a free-text query, greatly enhancing schema's minimal info.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb (search/resolve) and resource (names/symbols to IDs across coins, exchanges, categories, NFTs). Distinguishes from sibling tools by emphasizing it's the first step when ID is unknown.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly tells when to use: 'ALWAYS use this first when the user mentions a coin/exchange/NFT by name or ticker symbol and you don't already know the canonical CoinGecko ID.' Also notes that most other tools require IDs, providing clear context for alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Despite no annotations, the description fully discloses behavior: it notes cache may serve stale data up to TTL, counters are cumulative since process start, and provides detailed return structure. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with a brief line, bulleted usage cases, and a clear dict description. Every sentence adds value, no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains each parameter: symbol (CCXT unified format, example), exchange_ids (comma-separated, capped at 10, default), depth (levels per side, clamped, default). This adds meaning beyond the schema's defaults and types.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Describes the tool as fetching L2 order books from multiple exchanges in parallel and merging them into one virtual book. It explicitly differentiates from the sibling tool `get_orderbook` by stating it is 'more useful than per-venue get_orderbook for execution analysis', and explains that the merged book retains source exchange information for liquidity attribution.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
