## Description

This MCP server provides currency exchange rate data and conversion capabilities through the Frankfurter API, offering tools for retrieving supported currencies, latest exchange rates, historical rate data, and currency conversion for both current and specific dates. Built by Anirban Basu using Python with FastMCP, it features comprehensive environment variable configuration for API endpoints and HTTP client settings, SSL certificate support for self-signed certificates and proxy servers, optional response metadata inclusion for API call details, and dynamic composition support for mounting with other MCP servers. The implementation includes Docker containerization, extensive testing with pytest, a command-line interface for tool exploration, optional LlamaIndex integration for demonstration purposes, and supports multiple transport protocols (stdio, SSE, streamable-http), making it valuable for financial applications, currency analysis workflows, and building AI assistants that need reliable foreign exchange data without manual rate lookups.
