What is the Unirate MCP MCP server?

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.

What the server does

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.

Available tools

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 rate
  • latest_rate — The latest_rate tool exposed by this server
  • list_currencies — Returns the array of supported currency codes (170+) with no parameters. Useful for autocomplete or validating user-supplied codes

Credentials and setup notes

Configuration 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.

Installation

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.

Where it fits

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.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Unirate MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (convert, latest_rate, list_currencies) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Unirate MCP directly.
