timeout_member · Discord MCP Server MCP: Risk & Policy

WHAT IT DOES

What timeout_member does on Discord MCP Server

AI agents invoke timeout_member to trigger actions in Discord MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why timeout_member needs a policy

This tool triggers an external moderation action on Discord — restricting a member's ability to participate in the guild. It is not a simple data write (it enforces a permission restriction on a real user), not fully destructive (it is temporary and reversible), but it executes an operational action with significant social/community impact. Misuse could silence legitimate members, constituting high blast radius.

From the tool's definition Temporarily prevent a member from interacting in the guild (sending messages, reacting, joining voice). Provide duration_seconds to set a timeout, or remove an existing timeout.

timeout_member Rate-limited

timeout_member stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
