Magg MCP Server

A Model Context Protocol server that manages, aggregates, and proxies other MCP servers, enabling LLMs to dynamically extend their own capabilities. Its 14 documented tools cover magg, servers, kit, server. It runs locally over stdio via the published package.

People connecting cloud infrastructure tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Magg

before you install - you'll need

Set MAGG_JWT, MAGG_PRIVATE_KEY before connecting.

Claude Code

claude mcp add sitbon-magg -- uvx magg

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "sitbon-magg": {
      "command": "uvx",
      "args": [
        "magg"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license AGPL-3.0 - declared in the repository

pypi package magg - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.sitbon is GitHub-verified and matches the repo owner
