2. Configure your MCP client

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

{
  "mcpServers": {
    "congressmcp": {

      "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"
      }
    }
  }
}
