longRunningOperation · My MCP: Risk & Policy

WHAT IT DOES

What longRunningOperation does on My

AI agents invoke longRunningOperation to trigger actions in My. 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 longRunningOperation needs a policy

The tool executes a long-running operation, which suggests it runs some process or computation. The description is vague about what the operation does, but 'long-running operation' implies active execution rather than a simple read or write. Confidence is moderate due to the lack of specific details about what is actually executed.

From the tool's definition 'long-running operation with progress notifications' — implies execution of a process or task over time

Verdict

longRunningOperation Rate-limited

longRunningOperation 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.
