Tctc MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 54 installs a week from npm. Last commit 14 Sep 2026.

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 child = spawn(config.server.command, config.server.args, {
"0x608060405234801561000f575f5ffd5b506040516118e03803806118e083398101604081905261002e91610107565b60408051602081019091525f8152339061004781610092565b506001600160a01b03811661007557604051631e4fbdf760e01b81525f600482015260240160405180910390fd5b61007e816100a2565b50600461008b828261023…

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.
