WHAT IT DOES

What fw_resume does on Crow

AI agents invoke fw_resume to trigger actions in Crow. 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 fw_resume is rated High

This tool triggers an external operation (resuming audio playback on a hardware device - glasses). It has side effects on a physical/external system, fitting the Execute category. Misuse could disrupt user experience but has limited blast radius.

RECOMMENDED RULE

The rule that runs fw_resume safely

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

fw_resume Rate-limited

fw_resume 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 Crow, apply this rule, and every fw_resume call is checked against it from then on.
