resume_task · Schedule Task MCP: Risk & Policy

WHAT IT DOES

What resume_task does on Schedule Task MCP

AI agents use resume_task to create or update resources in Schedule Task MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Schedule Task MCP environment.

WHY IT NEEDS A POLICY

Why resume_task needs a policy

resume_task modifies the state of an existing task by re-enabling it and recalculating its schedule. This is a reversible state change (the task can be paused again), making it a Write operation. The medium severity reflects that resuming a task could trigger automated AI agent invocations on a schedule, which may have downstream effects depending on what the task does.

Verdict

resume_task Rate-limited

resume_task stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
