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 β real names on hearing testimony, not "Speaker A/B"
- All 50 states β not just federal, not just one state
- Historical depth β multiple years of legislative sessions
- Authenticated + rate-limited β production-ready for team workflows
No other MCP server has speaker-attributed state legislative hearing transcripts.
