LibraryAPI is a Model Context Protocol (MCP) server: US public libraries and branches near any address, with collections from the IMLS survey. 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 Python package libraryapi-mcp (via uvx) speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need LIBRARYAPI_KEY. The current release is v0.1.2, with source at library-api/libraryapi-mcp on GitHub.
You'll find LibraryAPI 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.
