Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

  const match = /^gid:\/\/Jobber\/(\w+)\/(\d+)$/.exec(Buffer.from(id, "base64").toString());

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(process.execPath, ["--import", import.meta.resolve("tsx"), server], {

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Optional settings from the registry entry, left out of the block above: FIELDTWIN_PORT (The port the twin listens on. The MCP server starts a twin of its own, so pick another port if one already runs on 4010), FIELDTWIN_HOST (The address the twin listens on. Keep the loopback address unless something else must reach the twin), FIELDTWIN_AUTH (any-token accepts any Bearer token; oauth accepts only tokens from the twin's OAuth endpoints), FIELDTWIN_SEED (Which fake business to generate: the same seed builds the same world).
