WHAT IT DOES

What detach does on Frida Agent MCP

AI agents invoke detach to trigger actions in Frida Agent MCP. 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 detach is rated High

This tool terminates an active Frida instrumentation session and unloads injected scripts. It triggers an external operation (detaching from a process and unloading code) that has side effects on the target process's instrumentation state.

RECOMMENDED RULE

The rule that runs detach safely

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

detach Rate-limited

detach 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 Frida Agent MCP, apply this rule, and every detach call is checked against it from then on.

FAQ

Questions about detach

What does the detach tool do? +

Detach from the current session and unload any injected scripts. It is categorised as a Execute tool in the Frida Agent MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on detach? +

Register the Frida Agent MCP server in PolicyLayer and add a rule for detach: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Frida Agent MCP. Nothing to install.

What risk level is detach? +

detach is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit detach? +

Yes. Add a rate_limit block to the detach rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block detach completely? +

Set action: deny in the PolicyLayer policy for detach. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides detach? +
