getBRC20TokenInfoFetch protocol + market metadata for a single BRC-20 token by ticker: current USD price, total supply, max supply, mint progress, holder count, and market cap.
| Name | Required | Description | Default |
|---|---|---|---|
| ticker | Yes | BRC-20 token ticker, typically 4 characters (e.g. 'ORDI', 'SATS'). Case-insensitive. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, establishing a safe read operation. The description adds the returned data fields but provides no further behavioral details such as error handling, rate limits, or response format. It does not contradict annotations.
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, well-structured sentence that front-loaded the verb and resource, followed by a list of returned fields. No filler or redundant content.
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 single-parameter tool with no output schema, the description enumerates all key return values (price, supplies, mint progress, holders, market cap), covering essential information. Combined with strong annotations, this is sufficient.
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 fully describes the ticker parameter with details on typical length and case-insensitivity, achieving 100% coverage. The description merely restates 'by ticker' without adding extra meaning, so the baseline of 3 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 states a specific verb ('Fetch') and resource ('protocol + market metadata') scoped to a single BRC-20 token by ticker, listing concrete fields returned. This clearly differentiates it from sibling tools like getBRC20Activity (activity) or listBRC20Tokens (listing).
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 context is clear: use this tool to fetch metadata for one BRC-20 token by ticker. However, it does not explicitly mention alternatives or when-not-to-use, unlike the highest-calibrated examples. Still, the scope is unambiguous.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
With 113 tools spanning many chains and asset classes, there is substantial overlap. For example, listPositions and getAllPositions appear to serve the same function, and there are many balance, token discovery, and collection data tools that differ mostly by chain or protocol, making misselection likely.
Naming conventions are inconsistent: most tools use camelCase with a verb (baseGetBalances, ethSwapQuote), but some use underscores (nansen_defi_portfolio), others are just bare nouns (wallet, rugcheck), and there are irregularities like solanaBalances instead of solanaGetBalances, plus hederaTokensSwapQuote vs. baseSwapQuote.
The server exposes 113 tools, far beyond the typical well-scoped set. This is an extreme mismatch with the apparent purpose of a wallet/swap server, making discovery and selection difficult for agents.
While the server offers extensive read-only data (balances, market data, NFTs, positions), it lacks core write operations: there is no actual swap execution or token transfer tool, and the referenced emblemCreateVault tool is missing. These are significant gaps that will prevent agents from completing common wallet actions.
