Capabilities

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.

Runs an external command .agents/plugins/codexbox/bin/cli.js:40

const result = spawnSync(process.execPath, args, { stdio: "inherit" });

# codex CLI — pinned npm global install, into a prefix `aicode` owns.

# `codex update` (and the TUI's "Update available!" prompt) shells out to

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.

Codexbox — questions

Answers built from our own checks of this server.

Why is there no uptime for Codexbox?

Codexbox runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.

Is Codexbox open source?

No, and the distinction matters: its licence is declared as WTFPL. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
