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.
