About Federal Register API MCP Server
Empower your AI agent to orchestrate your entire public policy research and document auditing workflow with the Federal Register API, the authoritative source for United States government rules and notices. By connecting the Federal Register to your agent, you transform complex administrative searches into a natural conversation. Your agent can instantly retrieve active document details, audit agency publications, and query specific rule metadata without you ever touching a government portal. Whether you are conducting regulatory research or managing regional policy constraints, your agent acts as a real-time administrative consultant, ensuring your data is always verified and precise.
GitHub Copilot Agent mode brings Federal Register API data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 4 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
What you can do
- Document Auditing — Search for thousands of public documents and rules by keyword and retrieve detailed metadata, including publication dates and agencies.
- Agency Oversight — Audit all US government agencies that publish in the Federal Register to understand the administrative reach of public sector rules instantly.
