What is Congress.gov MCP Server?

An unofficial MCP server that wraps the Congress.gov API. 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.

常见问题

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.
