About GovInfo MCP Server
Connect to the official GovInfo API and empower your AI agent with direct access to official publications from all three branches of the US Federal Government. Query congressional bills, federal regulations, court opinions, and presidential documents using natural language without navigating complex government databases.
LlamaIndex agents combine GovInfo tool responses with indexed documents for comprehensive, grounded answers. Connect 8 tools through the Vinkius and query live data alongside vector stores and SQL databases in a single turn — ideal for hybrid search, data enrichment, and analytical workflows.
What you can do
- Document Discovery — List available document collections and find specific packages based on date ranges or collection codes (e.g., BILLS, FR, CHRG)
- Deep Search — Perform complex searches across the entire GovInfo database to find relevant legislative or regulatory documents
- Daily Updates — Retrieve a list of all documents officially published on a specific date
- Metadata Extraction — Get detailed summary metadata for specific packages or their sub-documents (granules)
- Contextual Relationships — Discover related documents to understand the legislative or regulatory history of a specific bill or rule
The GovInfo MCP Server exposes 8 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
