Model Shunt runs on your own machine — the client starts it, so there is no endpoint to ping. 116 installs a week from pypi. Last commit 28 Sep 2026.
Model routing for AI agents: delegate bulk reads & boilerplate to cheap worker models.
What the code does
We read the source, 2 d 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.
const probe = spawn(candidate, ["-c", "import sys; sys.exit(0 if sys.version_info >= (3, 9) else 1)"], {
p = subprocess.Popen([hook_size], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)

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.
