getCoinById

Read-onlyIdempotent

Get descriptive project information about a coin: description, links, team and tags. Use for 'tell me about Uniswap', 'what is this project'. Does NOT include price; for price and market cap use getTickersById. Read-only; coinId is a canonical id (resolve with resolveId). No API key required.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`coinId`	Yes	Canonical CoinPaprika coin slug in 'symbol-name' format, e.g. 'btc-bitcoin', 'eth-ethereum', 'ada-cardano'. Do NOT pass ticker symbols ('BTC', 'AAVE') or guess the slug — it is not derivable from the symbol (e.g. AAVE resolves to 'aave-new', which you could not guess). Call search or resolveId first to resolve a symbol or name to its canonical id.
`rationale`	Yes	REQUIRED. In 1-2 sentences explain WHY you are calling this tool and what you intend to do with the result. Examples: 'User asked for BTC price; calling getTickersById to fetch current USD value.' 'Building a portfolio dashboard; need OHLCV for ETH last 7 days.' This is logged and reviewed to improve the MCP. Do not include user PII or secrets — use generic descriptions.

A4.7/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already confirm readOnlyHint=true, destructiveHint=false. The description adds valuable behavioral context: 'Read-only; coinId is a canonical id (resolve with resolveId). No API key required.' This goes beyond annotations and helps the agent understand constraints and safe usage.

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 clear and front-loaded with the core purpose. It consists of four sentences without fluff. Slightly longer than strictly necessary but still efficient 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 output schema, the description adequately explains what the tool returns (description, links, team, tags) and what it does not (price). It also covers usage context and prerequisites. Could mention error handling or pagination, but overall complete for its purpose.

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 100%, but the description adds crucial extra guidance: it explicitly warns against passing ticker symbols and advises using resolveId or search first. This adds semantic value beyond the schema's parameter 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 tool retrieves descriptive project information (description, links, team, tags) and provides example use cases ('tell me about Uniswap'). It distinguishes from getTickersById by explicitly noting it does NOT include price. This is specific and helps the agent select the right tool.

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 tells when to use this tool (for project info) and when not to (use getTickersById for price/market cap). It also instructs the agent to resolve coinId via resolveId or search, providing clear guidance on prerequisites and alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.9/5.0

Disambiguation4/5

Most tools have distinct purposes (e.g., getTickersById vs getTickersHistoricalById), but search and resolveId could cause confusion as both find entities. Overall, overlaps are minimal and well-documented.

Naming Consistency4/5

Core tools follow a consistent get[Resource][Modifier] camelCase pattern. Some utility tools (priceConverter, resolveId, search, keyInfo, submitFeedback, status) break the pattern, but they are clearly separate and the naming is still readable.

Tool Count3/5

With 31 tools, the server is comprehensive but slightly heavy. Some tools like getCoinOHLCVLatest, getCoinOHLCVToday, and getCoinOHLCVHistorical could potentially be merged, and the count feels at the upper bound for its scope.

Completeness4/5

The toolset covers a wide range of crypto data needs: current/historical prices, OHLC, exchanges, contracts, tags, people, global stats, search/resolution, and administrative functions. Only advanced features like news or portfolio tracking are missing.
