FrankfurterMCP MCP Server

If you want an AI assistant working directly with FrankfurterMCP, the frankfurtermcp mcp server is the bridge. MCP server acting as an interface to the Frankfurter API for currency exchange data.

What FrankfurterMCP does

Frankfurter is a useful API for latest currency exchange rates, historical data, or time series published by sources such as the European Central Bank. Should you have to access the Frankfurter API as tools for language model agents exposed over the Model Context Protocol (MCP), Frankfurter MCP is what you need.

Tools it exposes

Once connected, the assistant can call these 6 tools directly:

• get_supported_currencies — Get a list of currencies supported by the Frankfurter API
• get_latest_exchange_rates — Get latest exchange rates in specific currencies for a given base currency
• convert_currency_latest — Convert an amount from one currency to another using the latest exchange rates
• get_historical_exchange_rates — Get historical exchange rates for a specific date or date range in specific currencies for a given base currency
• convert_currency_specific_date — Convert an amount from one currency to another using the exchange rates for a specific date
• greet — Get a greeting from the FrankfurterMCP server. This is mostly used for internal testing

Installing the frankfurtermcp mcp server

The server is distributed via npm as @modelcontextprotocol/inspector, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

Before the server will start you need to supply 3 environment variables: FAST_MCP_HOST, FRANKFURTER_API_URL, FASTMCP_HOST. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. FrankfurterMCP sits in that group, and the shape of its toolset — get_supported_currencies, get_latest_exchange_rates, convert_currency_latest among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

• This is a hosted server — you point your client at an endpoint rather than running a local process, so there is nothing to keep updated on your machine.
• It will not start until its required credentials are present, so set those before wondering why the tools never appear.
• Written in Python.
• MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the frankfurtermcp mcp server actually does with your data.
• Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
