Model Context Protocol server for the UniRate API — currency conversion, exchange rates, historical data (back to 1999), and supported-currency
If you already use Unirate MCP, the unirate mcp mcp server is the piece that lets your assistant work with it directly. Model Context Protocol server for the UniRate API — currency conversion, exchange rates, historical data (back to 1999), and supported-currency lookup for AI assistants. Stdio + Streamable HTTP/SSE transports.
Most "currency for AI" workflows today involve hand-rolled fetch wrappers in custom tools, or generic HTTP MCP servers that hand the model raw JSON. This server gives models a tight, typed, currency-aware tool surface — they ask "what was 100 USD in EUR on 2020-03-15?" and get back a formatted answer plus a structured payload they can chain into other tool calls.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
convert — Convert an amount from one currency to another at the latest ratelatest_rate — The latest_rate tool exposed by this serverlist_currencies — Returns the array of supported currency codes (170+) with no parameters. Useful for autocomplete or validating user-supplied codesConfiguration is passed through the environment: UNIRATE_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Unirate MCP's toolset — convert, latest_rate, list_currencies — is a fair guide to whether it matches your workflow. It is maintained by unirate-api; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
