Federal Register — Claude Code MCP server: use and install
This MCP server lets an agent work with Federal Register rules, notices, executive orders, and FAR cases when regulatory documents need to be searched.
claude mcp add --transport http federal-register-mcp https://federal-register.1102tools.com/mcpWhat Federal Register does
Federal Register exposes eight tools for working with records from the publication. An agent can search proposed or issued rules, review notices, look up executive orders, and inspect FAR cases.
Claude Code can connect through the hosted MCP endpoint or run the server locally with uvx. The local option depends on uvx, so that setup will not work without the launcher. The server is also listed for Codex, Cursor, GitHub Copilot, Windsurf (Devin Desktop), Cline, Zed, and Gemini CLI.
