Delete simulator devices.
AI agents call simctl_delete_device to permanently remove resources in Simctl — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of simulator devices is an irreversible operation that removes virtual device configurations and associated data. This cannot be undone without recreating the device from scratch.
From the tool's definition Tool name 'simctl_delete_device' and description 'Delete simulator devices' explicitly indicate irreversible deletion of simulator instances.
Attacks that exploit this kind of access
Delete simulator devices. It is categorised as a Destructive tool in the Simctl MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Simctl MCP server in PolicyLayer and add a rule for simctl_delete_device: 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 Simctl. Nothing to install.
simctl_delete_device 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 simctl_delete_device 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 simctl_delete_device. 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.
simctl_delete_device is provided by the Simctl MCP server (nzrsky/simctl-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
