discord_login · MCP-Discord MCP: Risk & Policy

WHAT IT DOES

What discord_login does on MCP-Discord

AI agents invoke discord_login to trigger actions in MCP-Discord. 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 discord_login needs a policy

This tool initiates an authenticated session with Discord using a token, which is an external operation that establishes a live connection and enables all subsequent privileged actions. It's not merely reading data — it triggers an authentication/session establishment process with side effects (active bot session).

Verdict

discord_login Rate-limited

discord_login 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.
