Gavelin MCP Server provides AI tools with access to U.S. state-level legislative records, built on the Model Context Protocol (MCP). Its core data includes state legislature hearing transcripts with speaker attribution, as well as bill records covering all 50 U.S. states.
Purpose The service is designed to enable AI agents to search and retrieve legislative information from U.S. states, including bills, hearing testimony, committee hearing records, and the speaking activity of specific legislators or witnesses.
Key Capabilities

- Search hearing testimony: Search speaker-attributed hearing and floor session segments to find what a specific legislator or witness said on any topic, returning speaker name, role, committee, date, and context.
- Get bill details: Retrieve complete information about a specific bill, including sponsors, subjects, committees, legislative history, and any hearing mentions.
- Get speaker activity: Retrieve all remarks by a specific legislator or witness in hearings and floor sessions.
- Search committee hearings: Browse committee and public hearings by topic, committee, chamber, or date range.
- Get hearing transcripts: Retrieve the full transcript of a specific hearing, with all speakers labeled by name.
- List available states: See which states have data and what types of data (bills, transcripts, or both).
