Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability71
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 695 tokens (~99/item across 7 items; 7 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the exchangerate.dev MCP server?
exchangerate.dev is a hosted endpoint at https://api.exchangerate.dev/v1/mcp/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
convert ~61
Convert an amount from one currency to another at the current rate. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | – | yes | – |
| from | string | yes | – |
| to | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_range ~109
Get a daily time-series of exchange rates over a date range (business days). Capped at 366 rows per call; when has_more is true, pass next_cursor as the cursor parameter to fetch the next page. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading.
| Name | Type | Req | Description |
|---|---|---|---|
| base | string | yes | – |
| cursor | – | – | – |
| end_date | string | yes | – |
| start_date | string | yes | – |
| symbols | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_rate ~149
Get the current — or historical, with date — exchange rate from one currency to another. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading. Rates update ~60s for real-time currencies through the trading week when the live overlay is active; the source field on every response is the authoritative freshness indicator (live | ecb_daily | fred_daily | nbp_daily) — rates fall back to official daily reference data during market closures, data-source unavailability, or low liquidity. market_session on every response indicates open, weekend, or interbank_closed.
| Name | Type | Req | Description |
|---|---|---|---|
| base | string | yes | – |
| date | – | – | – |
| quote | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_usd_index ~85
Get the latest independently calculated USD index. dxy-reconstructed uses the published six-currency basket formula but is not official or licensed ICE data. usd-strength is the versioned exchangerate.dev equal-weight 13-currency index, with 2026-01-02 = 100. Both require a complete, time-aligned basket.
| Name | Type | Req | Description |
|---|---|---|---|
| index | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
list_currencies ~44
List all supported currencies with name, decimal precision, minor units, and whether the pair is derived (triangulated). Use this before other tools to discover valid currency codes.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
search_docs ~70
Search the exchangerate.dev FAQ corpus via BM25. Returns the top-K matching questions and answers with relevance scores. Use before answering how-to / pricing / data-sourcing questions so you cite the canonical text instead of guessing from training data.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| query | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
start_checkout ~67
Open a billing URL for an explicitly selected eligible plan. After human confirmation, a Free account without a subscription receives a one-hour Stripe Checkout URL; an existing Basic subscriber receives Stripe billing management instead. Cancellation creates nothing and account identifiers are never accepted from the model.
| Name | Type | Req | Description |
