toggle_queue · Ploi MCP Server MCP: Risk & Policy

WHAT IT DOES

What toggle_queue does on Ploi MCP Server

AI agents invoke toggle_queue to trigger actions in Ploi 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 toggle_queue needs a policy

This tool triggers an external operation (pausing or resuming a queue worker process) that affects running infrastructure. It does not merely read data, nor does it create/modify persistent data reversibly in the typical sense — it controls execution state of a service. Misuse could halt job processing or unexpectedly resume a paused queue, impacting application functionality.

From the tool's definition Pause or unpause a queue worker (single toggle — pauses if running, resumes if paused)

toggle_queue Rate-limited

toggle_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.
