The rule that runs console_inject_fetch_interceptor safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For console_inject_fetch_interceptor, this is the rule to start with:
console_inject_fetch_interceptor 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 Jshookmcp, apply this rule, and every console_inject_fetch_interceptor call is checked against it from then on.
