Kill a process by PID.
AI agents call kill_process to permanently remove resources in Frida MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Killing a process forcibly terminates it, destroying its runtime state, any in-memory data, and potentially causing data loss or service disruption. This is an irreversible action with a high blast radius if misused, especially in the context of a dynamic instrumentation server that may be attached to critical or production processes.
From the tool's definition 'Kill a process by PID' — terminating a process is irreversible and cannot be undone; the process and any unsaved state are permanently destroyed.
Attacks that exploit this kind of access
Kill a process by PID. It is categorised as a Destructive tool in the Frida MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Frida MCP Server MCP server in PolicyLayer and add a rule for kill_process: 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 MCP Server. Nothing to install.
kill_process is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the kill_process 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 kill_process. 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.
kill_process is provided by the Frida MCP Server MCP server (nonsleepr/frida-mcp.ts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
