Gavelin is a Model Context Protocol (MCP) server: Search bills and speaker-attributed hearing transcripts across all 50 US state legislatures. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://mcp.gavelin.ai/mcp and you're connected, with nothing to install locally. The current release is v1.0.0, published under the MIT license, with source at gavelin-ai/mcp on GitHub.
You'll find Gavelin 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.
