getCoinExchanges

Read-onlyIdempotent

List the exchanges that LIST a specific coin (venue names only). Use for 'which exchanges list X', 'is X on Coinbase', 'where is X listed'. For where to BUY with per-market price and volume use getCoinMarkets; for the live price use getTickersById. Read-only; coinId is a canonical id, limit caps results. No API key required.

Input Schema

NameRequiredDescriptionDefault
limitNo
coinIdYesCanonical 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.
rationaleYesREQUIRED. 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.

TDQS

A4.6/5.0
Behavior4/5

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

Annotations already carry the full safety profile (readOnly, idempotent, non-destructive, open-world), so the description is not the only source. It still adds real context: results are venue names only, no API key is required, and limit caps the result set. 'Read-only' and 'coinId is a canonical id' partly restate structured data, keeping it just below a 5.

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?

Four sentences, front-loaded with purpose, then routing, then constraints. Efficient overall, though 'Read-only' and the canonical-id reminder overlap with the annotations and schema and could be trimmed.

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?

Output schema exists, so return-value explanation is unnecessary; the description still notes 'venue names only'. With three parameters, one of them undocumented in schema, and rich annotations, the description covers routing, auth requirements, and the limit semantics — nothing an agent needs to call it correctly is missing.

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 67%; coinId and rationale are thoroughly documented in the schema, but `limit` has no schema description. The description fills that gap by saying limit caps results, and reinforces the canonical-id constraint that the schema also states. It adds meaning for the undocumented parameter rather than merely echoing 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?

States a specific verb and resource ('List the exchanges that LIST a specific coin') and immediately qualifies the scope with '(venue names only)'. It is clearly separable from getCoinMarkets and getTickersById, which are named explicitly.

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?

Gives concrete user phrasings that should route here ('which exchanges list X', 'is X on Coinbase', 'where is X listed') and then names the two alternatives with the condition that selects each (per-market price/volume vs. live price). This is explicit when-to-use plus when-to-use-something-else.

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