WHAT IT DOES

What frida_unload_script does on Ya Frida

AI agents invoke frida_unload_script to trigger actions in Ya Frida. 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 frida_unload_script is rated High

Unloading a Frida script terminates an active instrumentation session injected into a running process. This is an operational action that affects live process execution and instrumentation state. While it doesn't delete data permanently (not Destructive), it triggers an external operation against a running process by removing injected code, which falls under Execute.

RECOMMENDED RULE

The rule that runs frida_unload_script safely

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

frida_unload_script Rate-limited

frida_unload_script 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.
