# Gavelin MCP Server

**State legislative intelligence for AI agents.** The only MCP server with speaker-attributed hearing transcripts from US state legislatures.

## What Makes This Different

Every government affairs team will have AI agents doing policy research. Those agents need clean, structured legislative data. Gavelin is the access layer.

- **Speaker attribution** — real names on hearing testimony, not "Speaker A/B"
- **All 50 states** — not just federal, not just one state
- **Historical depth** — multiple years of legislative sessions
- **Authenticated + rate-limited** — production-ready for team workflows

No other MCP server has speaker-attributed state legislative hearing transcripts.
