Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
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.
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.

This one needs environment variables set before it will start:
MARKLAYER_ROOM (Same as --room: the share URL or room id to join at startup.), MARKLAYER_API_BASE (Override the MarkLayer worker base URL. Defaults to https://marklayer.app; useful against a local dev worker.), MARKLAYER_AGENT (Name shown to the humans in the room for this agent. Defaults to claude-code.).
The author declared them in the registry entry; get the values from the project itself.
