Django Chainsaw runs on your own machine — the client starts it, so there is no endpoint to ping. 174 installs a week from pypi. Last commit 9 Oct 2026.
Finds what will hurt in a Django project: cascades, N+1, unsafe migrations, tenant leaks.

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.
module = __import__(settings.SETTINGS_MODULE, fromlist=["__file__"])

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.

}Put your own values in place of
<DJANGO_CHAINSAW_PROJECT_PATH> (Absolute path to the Django project to analyse - the directory containing manage.py, or whichever directory the settings module is importable from. This server must run in an interpreter that can import that project, so install it into the project's own environment rather than an isolated one), <DJANGO_CHAINSAW_SETTINGS_MODULE> (Dotted path to the settings module, for example myproject.settings. Point it at the settings the site actually runs on: a base or partial module can import cleanly and load no models, and the server says so when that happens).
The author’s registry entry marks them as required.
