resume_loop · Scrumdo MCP: Risk & Policy

WHAT IT DOES

What resume_loop does on Scrumdo

AI agents invoke resume_loop to trigger actions in Scrumdo. 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 resume_loop needs a policy

This tool triggers re-execution of a paused or escalated process loop ('re-enter the driver'), which constitutes running/triggering an external operation. It is not simply reading or writing data, but resuming an ongoing automated workflow. Severity is medium since resuming a loop could have downstream effects depending on the workflow state, but the description is sparse, lowering confidence.

Verdict

resume_loop Rate-limited

resume_loop 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.
