It lets you query U.S. congressional data—bills, members, committees, votes, hearings, and more—through natural language using any MCP-compatible client. Intended for developers and anyone who wants programmatic access to legislative information.

How to use Congress.gov MCP Server?

Install dependencies with uv sync, obtain a free Congress.gov API key, and add it to a .env file. Then configure an MCP client (e.g., Claude Desktop or Claude Code) to launch server.py via uv run, pointing to the .env file.

FAQ from Congress.gov MCP Server

Is this an official Congress.gov product?

No. This is an unofficial MCP server and is not affiliated with or endorsed by Congress.gov or any U.S. government agency.

What are the prerequisites to use this server?

You need uv installed and a free Congress.gov API key (sign up at api.congress.gov/sign-up/).

How do I configure it for Claude Desktop?

Add a congress_gov_mcp entry to the mcpServers object in your Claude Desktop config file, with command set to the absolute path of uv and args including run, --env-file, the path to your .env, and the path to server.py.

How do I configure it for Claude Code?

Add a congress_gov_mcp entry to .mcp.json in the directory where you run Claude Code, following the same structure as the Claude Desktop config but using uv as the command directly.

What transport and authentication does the server use?

The server communicates via the MCP standard transport (stdio). Authentication is handled by an API key passed through the CONGRESS_GOV_API_KEY environment variable.
