Quick Start

1. Get a free Congress.gov API key

Sign up at api.congress.gov/sign-up (takes 30 seconds, completely free).

2. Configure your MCP client

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "congressmcp": {
      "command": "uvx",
      "args": ["congressmcp"],
      "env": {
        "CONGRESS_API_KEY": "your-api-key-here"
      }
    }
  }
}

VS Code — add to .vscode/mcp.json:

{
  "servers": {
    "congressmcp": {
      "command": "uvx",
      "args": ["congressmcp"],
      "env": {
        "CONGRESS_API_KEY": "your-api-key-here"
      }
    }
  }
}

Cursor — add to ~/.cursor/mcp.json using the same format as VS Code.

3. Start asking questions

"Find recent climate change bills in the 119th Congress" "How did senators from California vote on the latest defense bill?" "Who are the members of the Senate Judiciary Committee?" "What's the latest action on H.R. 1234?"
