Returns

{entries:[{id, target_id, user_id, action_type, reason}], count}. Structured reason values remain raw moderator-controlled data; the human-readable text response fences them.

Example structured result

      "id": "123456789012345678",

Access and common errors

• The audit_log category must be enabled by MCP_CATEGORIES when an allowlist is set.
• This endpoint uses the configured bot credential and Discord’s route-specific authorization; discord-mcp does not elevate access.
• An invalid credential returns a 401-class tool error. Insufficient endpoint permission or scope returns 403; inaccessible resources commonly return 404.

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.
