WHAT IT DOES

What agent_cancel does on MCP Framework Personal

AI agents invoke agent_cancel to trigger actions in MCP Framework Personal. 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.

RISK

Why agent_cancel is rated High

Cancelling a job is an action that triggers an external operation (stopping/terminating a running job). It is not purely a read, and while it could be considered partially destructive, job cancellation is typically a recoverable state change rather than irreversible deletion. It falls best under Execute as it triggers an operational side effect on a running process.

From the tool's definition Cancela un job por ID (Cancels a job by ID)

RECOMMENDED RULE

The rule that runs agent_cancel safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MCP Framework Personal, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For agent_cancel, this is the rule to start with:

agent_cancel Rate-limited

agent_cancel 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.
