AI agents may call reset_device_emulation to permanently remove or destroy resources in Safari DevTools MCP. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call reset_device_emulation in a loop, permanently destroying resources in Safari DevTools MCP. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access reset_device_emulation gives an agent. Each links to the full case and the policy that stops it:
Other destructive tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
Remove all device emulation overrides and restore the original. It is categorised as a Destructive tool in the Safari DevTools MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Safari DevTools MCP server in PolicyLayer and add a rule for reset_device_emulation: 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 Safari DevTools MCP. Nothing to install.
reset_device_emulation 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 reset_device_emulation 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 reset_device_emulation. 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.
reset_device_emulation is provided by the Safari DevTools MCP server (safari-devtools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
