What toggleProxy does on Whistle
AI agents invoke toggleProxy to trigger actions in Whistle. 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 toggleProxy is rated High
This tool toggles the proxy server on or off, which is an operational state change that affects all network traffic routing through it. It triggers an external system state change rather than simply reading or writing data. Misuse could disrupt network connectivity or silently redirect traffic, making the blast radius high.
From the tool's definition '启用或禁用whistle代理' (Enable or disable whistle proxy)
Attacks that exploit this kind of access
The rule that runs toggleProxy safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Whistle, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For toggleProxy, this is the rule to start with:
toggleProxy 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Whistle, apply this rule, and every toggleProxy call is checked against it from then on.
