How to install m3

m3 is published on PyPI as m3-mcp, and it depends on fastmcp. 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 uv for uvx.
Add it to Claude Code from a terminal:
```
claude mcp add m3 -- uvx m3-mcp
```

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

{
  "mcpServers": {
    "m3": {
      "command": "uvx",
      "args": [
        "m3-mcp"
      ]
    }
  }
}

Restart the client and check it. Run claude mcp list, or open the client's MCP settings, and confirm m3 and its tools are listed. The install guide covers VS Code and Codex.
