AI agents may call clear_display to permanently remove or destroy resources in agentView. 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 clear_display in a loop, permanently destroying resources in agentView. 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 clear_display 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.
Removes the current live content from a display and returns it to its idle/default state. Viewers will immediately see the change. Use this when the user wants to blank or reset a display. This does not delete the display itself — use delete_display for that. Requires authentication with at least content_only scope. Returns id and status ('cleared').. It is categorised as a Destructive tool in the agentView MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the agentView MCP server in PolicyLayer and add a rule for clear_display: 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 agentView. Nothing to install.
clear_display 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 clear_display 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 clear_display. 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.
clear_display is provided by the agentView MCP server (https://agentview.de/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
