The panel as an agent (MCP)

The panel can talk to an assistant — Claude, or any other MCP client. Not by scraping screens: it has an interface of its own that says what it can do, so the assistant does not have to guess.

What it is good for: "restart Survival and tell me what it got stuck on", "back up every server before I touch the modpack", "why did Creative not come up".

Turning it on

Admin → Application API. Until a key is configured the screen says so outright — and the whole surface answers 404 from outside, so it cannot be told apart from one that does not exist. That is deliberate.

It is switched on by adding STYGION_MCP_KEY to the env file and restarting the panel; the installer has generated one since 0.3.0:

grep STYGION_MCP_KEY /etc/stygion/*.env

With a key, the screen shows the address an assistant connects to and how many tools the panel offers it. The key itself is behind a second click, and revealing it is written to the activity log.

What the assistant may do

What the key may. No more.

Think of a key as an account, not a switch: everything done with it appears in that server's activity — under the key, not under you. If something happens, it is visible that an agent did it.

A tool calls the same service the panel does, so a rule the panel enforces is a rule the assistant is held to as well. No back doors.

Revoking

A key can be revoked. A revoked key stops working immediately, even mid-task.

Revoke one when you have stopped using that client, when it has been on somebody else's machine, or simply now and then. Issuing a new one takes seconds — far cheaper than wondering where the old one ended up.
