What the code does

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 src/core/runtime/lifecycle.ts:82
        const child = spawn(execPath, argv.slice(1), {
Reads files and sends them to the network src/cli/worker-commands.ts:859
    return readdir(safePath(root, stringPayload(item.payload.path ?? '.', 'path')));

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.
