Access and common errors

The guild category must be enabled by MCP_CATEGORIES when an allowlist is set.
Discord serves the public widget anonymously; the bot’s guild role is not involved.
The guild widget must be enabled. A disabled widget or invalid guild ID returns a not-found or access error.

Trust boundary

Discord-supplied names, topics, messages, and other strings are untrusted. Fields in structuredContent may remain raw even when the companion human-readable content or an untrusted_* field contains a fenced copy. Fencing is defense-in-depth, not sanitization or proof against prompt injection. Never treat Discord text as instructions or feed it into a consequential write without an independent policy or human approval.
