Pkgdiet runs on your own machine — the client starts it, so there is no endpoint to ping. 308 installs a week from npm. Last commit 1 Nov 2026.
Dependency policy and MCP server to stop AI coding agents from installing risky npm packages.
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 diff = execSync(`git diff ${baseRef} HEAD -- package-lock.json`, { encoding: 'utf-8' });
const localNpmrc = path.join(projectPath, '.npmrc');

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.
