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/server/ui.ts:244
  const child = spawn(command, args, { detached: true, stdio: 'ignore' });
Secret passed into the image build Dockerfile:69
ENV SAP_PASSWORD=""
Touches key and credential files mta.yaml:84
        - .npmrc

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.

ARC-1 — questions

Answers built from our own checks of this server.

Why is there no uptime for ARC-1?
ARC-1 runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is ARC-1 open source?
Yes — it is published under the MIT licence, written in TypeScript, 198 stars on GitHub and 6 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
