AI agents may call clean_text to permanently remove or destroy resources in Structured Data Validator. 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 clean_text in a loop, permanently destroying resources in Structured Data Validator. 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 clean_text gives an agent. Each links to the full case and the policy that stops it:

Remove HTML tags, fix encoding issues, normalize whitespace, and extract clean text from messy input. Perfect for agents processing scraped web content or user-submitted text.. It is categorised as a Destructive tool in the Structured Data Validator MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Structured Data Validator MCP server in PolicyLayer and add a rule for clean_text: 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 Structured Data Validator. Nothing to install.
clean_text 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 clean_text 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 clean_text. 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.
clean_text is provided by the Structured Data Validator MCP server (@agenson-horrowitz/structured-data-validator-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
