WHAT IT DOES

What stop_caido_service does on Pentester-MCP

AI agents invoke stop_caido_service to trigger actions in Pentester-MCP. 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 stop_caido_service is rated High

This tool triggers an external operation (process termination) whose effects depend on the PID argument provided. While termination is somewhat reversible (the service can be restarted), it still represents active execution of system commands that disrupt running services. It does not fit Destructive (data is not permanently lost), but clearly exceeds Write (it's not creating/modifying data reversibly).

From the tool's definition Tool description states it 'Terminates a running Caido service process using its PID' — this executes a termination command with external operational effects (stopping a service).

RECOMMENDED RULE

The rule that runs stop_caido_service safely

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

stop_caido_service Rate-limited

stop_caido_service 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.
