Skarn runs on your own machine — the client starts it, so there is no endpoint to ping. 57 installs a week from npm. Last commit 4 Oct 2026.
Scans AI coding sessions and assistant configs for leaked secrets and risky hooks; local, redacted
What the code does

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 res = spawnSync(binPath, process.argv.slice(2), { stdio: "inherit" });
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
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.
