1. Get your API key:

   • Visit: https://congressmcp.lawgiver.ai
   • Sign up for a free account

2. Configure local MCP client:

Add this to your config or cline_mcp_settings.json with your API key:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "congressmcp": {
      "command": "npx",
      "args": [
        "-y", 
        "congressmcp"
      ],
      "env": {
        "CONGRESSMCP_API_KEY": "your-api-key-here"
      }
    }
  }
}

3. Restart Claude Desktop to activate the connection.

Usage

Ask Claude about:

• Bills: "Search for recent climate bills"
• Members: "Who represents California in the Senate?"
• Committees: "What committees handle healthcare?"
• Amendments: "Show amendments to HR 1234"
• Roll Call Votes: "How did senators vote on the infrastructure bill?"
• And much more legislative data!

Alternative Installation: Self-Hosted

For advanced users who want full control, CongressMCP is open source:

• Clone the CongressMCP repository
• Requires Python environment + database setup
• Congress.gov API key needed
• See CongressMCP/README.md for technical details

Note: Self-hosting requires significant technical setup and maintenance. The hosted service (above) provides better reliability and support for most users.
