AI agents may call text_truncate to permanently remove or destroy resources in UnClick. 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 text_truncate in a loop, permanently destroying resources in UnClick. 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.

Truncate text to a maximum length.. It is categorised as a Destructive tool in the UnClick MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the UnClick MCP server in PolicyLayer and add a rule for text_truncate: 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 UnClick. Nothing to install.
text_truncate 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 text_truncate 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 text_truncate. 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.
text_truncate is provided by the UnClick MCP server (creativelead/unclick). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
