LexAPI

Overview

LexAPI is a Model Context Protocol (MCP) server: Search EUR-Lex, fetch parsed EU legislation and case law, explore the citation graph. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package @lexapi/mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need LEXAPI_API_KEY. The current release is v0.1.3, published under the MIT license, with source at Lex-API/lexapi-mcp on GitHub.

You'll find LexAPI in the Development category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
