RECOMMENDED RULE

The rule that runs frida_memory_read 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 frida_memory_read, this is the rule to start with:

frida_memory_read Allowed

frida_memory_read is read-only, so it stays allowed. 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 frida_memory_read call is checked against it from then on.
