How to install us-gov-open-data-mcp

us-gov-open-data-mcp is published on npm as @iflow-mcp/lzinga-us-gov-open-data-mcp, and it is listed in the official MCP Registry. These steps assume it runs as a local stdio server, which is the usual setup.

Check the README. Confirm the start command and note any API keys or environment variables it needs (pass them with -e KEY=value or an env block). You need Node.js for npx.

Add it to Claude Code from a terminal:

claude mcp add us-gov-open-data-mcp -- npx -y @iflow-mcp/lzinga-us-gov-open-data-mcp

Or add it to Cursor or Claude Desktop in .cursor/mcp.json or claude_desktop_config.json:

{
  "mcpServers": {
    "us-gov-open-data-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@iflow-mcp/lzinga-us-gov-open-data-mcp"
      ]
    }
  }
}

Restart the client and check it. Run claude mcp list, or open the client's MCP settings, and confirm us-gov-open-data-mcp and its tools are listed. The install guide covers VS Code and Codex.
