4da MCP Server runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 11 Sep 2026.
Dependency intelligence for AI agents. CVE scanning, health checks, upgrade planning.

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.
this.process = cp.spawn(nodePath, [serverPath], {
__APP_VERSION__: JSON.stringify(process.env.npm_package_version || '1.0.0'),

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.
