AI agents call get_script_output to retrieve information from Frida without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_script_output retrieves data that has been accumulated from a previously loaded Frida script. It is a passive read operation that queries output without side effects. While Frida itself enables dynamic code instrumentation (which is powerful), this specific tool only reads and returns the results of operations performed by other tools (load_script, call_rpc, attach).
From the tool's definition Tool name and description indicate 'Retrieve accumulated messages' from a Frida instrumentation script, with no modifications, deletions, or code execution triggered by this call.
Attacks that exploit this kind of access
Retrieve accumulated messages (. It is categorised as a Read tool in the Frida MCP Server, which means it retrieves data without modifying state.
Register the Frida MCP server in PolicyLayer and add a rule for get_script_output: 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. Nothing to install.
get_script_output is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_script_output 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.
Set action: deny in the PolicyLayer policy for get_script_output. 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.
get_script_output is provided by the Frida MCP server (snowluma/mcp-frida). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_script_output is one line of Frida's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
