## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the currencylayer MCP by usefulapi server?

currencylayer MCP by usefulapi is a hosted endpoint at https://currencylayer.usefulapi.io/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.

## MCP tools (5)

### `currencylayer_get_live_rates` (~185 tokens)

Get live exchange rates

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Real-time exchange rates for up to 174 world currencies and precious metals relative to a source currency (default USD). Quotes are keyed by pair, e.g. USDEUR = 0.918 means 1 USD = 0.918 EUR. The free plan refreshes daily, higher plans hourly down to every 60 seconds. Use 'currencies' to limit the reply. GET /live.

Input parameters:

- `currencies` (array): Only these currency codes, e.g. ["EUR","GBP","JPY"] (default: all of them).
- `source` (string): Source (base) currency code, default USD. Needs the Basic plan or higher; every quote is then SOURCE+TARGET, e.g. EURGBP.

### `currencylayer_get_historical_rates` (~183 tokens)

Get historical exchange rates

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Exchange rates for one past date (data back to 1999 for most currencies; a currency added later has no data before its start date and the whole request then fails). Quotes are keyed by pair, e.g. USDEUR. Use 'currencies' to limit the reply. GET /historical.

Input parameters:

- `currencies` (array): Only these currency codes, e.g. ["EUR","GBP","JPY"] (default: all of them).
- `date` (string, required): The date to look up, yyyy-mm-dd.
- `source` (string): Source (base) currency code, default USD. Needs the Basic plan or higher; every quote is then SOURCE+TARGET, e.g. EURGBP.

### `currencylayer_convert_currency` (~152 tokens)

Convert an amount

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Convert an amount from one currency to another with real-time rates, or with the rates of a past date. Returns the result and the quote used. Needs the Basic plan or higher. GET /convert.

Input parameters:

- `amount` (number, required): Amount to convert (positive, up to 1e12).
- `date` (string): Use the rates of this date (yyyy-mm-dd) instead of real-time rates.
- `from` (string, required): Currency to convert from, e.g. USD.
- `to` (string, required): Currency to convert to, e.g. EUR.

### `currencylayer_get_timeframe_rates` (~217 tokens)

Get exchange rates for a date range

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Daily exchange rates for every date from start_date to end_date (at most 365 days apart), one entry per date. Needs the Enterprise plan or higher. The reply must stay small: days x currencies may not exceed 2000 (without 'currencies' that is 174 per day), checked before the request is sent. GET /timeframe.

Input parameters:

- `currencies` (array): Only these currency codes, e.g. ["EUR","GBP","JPY"] (default: all of them).
- `end_date` (string, required): Last date, yyyy-mm-dd (not before start_date, at most 365 days after it).
- `source` (string): Source (base) currency code, default USD. Needs the Basic plan or higher; every quote is then SOURCE+TARGET, e.g. EURGBP.
- `start_date` (string, required): First date, yyyy-mm-dd.

### `currencylayer_get_rate_changes` (~213 tokens)

Get exchange rate changes

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). How exchange rates changed between two dates: per currency pair the start_rate, end_rate, absolute change and change_pct. Pass both dates or none (none = yesterday's end-of-day rate against the latest rate). Forex markets are closed on weekends, so a weekend change can be zero. Needs the Enterprise+ plan or higher. GET /change.

Input parameters:

- `currencies` (array): Only these currency codes, e.g. ["EUR","GBP","JPY"] (default: all of them).
- `end_date` (string): End date, yyyy-mm-dd (give both dates or neither).
- `source` (string): Source (base) currency code, default USD. Needs the Basic plan or higher; every quote is then SOURCE+TARGET, e.g. EURGBP.
- `start_date` (string): Start date, yyyy-mm-dd (give both dates or neither).
