Reference Data is a Model Context Protocol (MCP) server: European govt data, cited: rates, VAT, tax, wages, holidays, FX. 35 countries; Germany free. In practice that means any MCP-compatible AI assistant can call Reference Data's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://euroref.dev/mcp and you're connected, with nothing to install locally. The current release is v1.5.0.
Reference Data is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
