pause-queue · Rabbitmq MCP: Risk & Policy

WHAT IT DOES

What pause-queue does on Rabbitmq

AI agents invoke pause-queue to trigger actions in Rabbitmq. 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 pause-queue needs a policy

Pausing a queue suspends message processing/delivery for that queue, which is an operational action with significant side effects — consumers stop receiving messages, potentially causing backlogs or service disruptions. It is not a simple data read or write, but an operational state change that triggers external effects.

Verdict

pause-queue Rate-limited

pause-queue 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.
