Magg runs on your own machine — the client starts it, so there is no endpoint to ping. 1 586 installs a week from pypi. Last commit 27 Sep 2026.
Aggregates and proxies other MCP servers, letting LLMs discover, add, and manage tools at runtime.
What the code does
We read the source, 6 h ago · rules 995398eba69f
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
exec(startup_code, self.console.locals)
USER root
auth_init.add_argument("--key-path", type=Path, help="Path for authentication keys (default: ~/.ssh/magg)")
RUN curl -LsSf https://astral.sh/uv/install.sh | sh

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
