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.

  return new MarkError("UPGRADE_REQUIRED", `${msg} Update Mark: ${up.command} (global install: ${up.global}). ${up.mcp} Mark never updates itself.`, { ...d, markVersion: MARK_VERSION, escrowUrl: url, upgrade: up });
