Currency and forex data your agent can call

Use the same exchangerate.dev data contract through MCP and REST. Every rate includes source and freshness context so an agent can explain what it retrieved. Free MCP rates arrive 15 minutes late, like other Free routes.

Questions about the MCP server

What is the exchangerate.dev MCP server URL?
Claude Code and other remote-MCP clients can connect directly to the first-party Streamable HTTP endpoint at https://api.exchangerate.dev/v1/mcp/ without installing a local package.
Can I try the FX MCP server without an API key?
Yes for the remote HTTP endpoint — anonymous requests use a shared, IP-capped pool so you can test the real tools and data before signing up. The local stdio bridge requires EXCHANGERATE_API_KEY by default; set ALLOW_ANONYMOUS=true instead to run it keyless on the same anonymous pool. Use a free API key for attributed quota, a higher rate ceiling, and production use.
Do MCP tool calls count against the REST API quota?
Yes. Each MCP tool call counts as one API call against the same per-minute rate limit and monthly quota as the corresponding REST request.
Are the exchange rates suitable for trading or settlement?
No. The rates are indicative developer-grade references for software, analytics, research, and display. They are not executable quotes and must not be used for settlement or regulated trading.
