AI agents may call cancel_intent to permanently remove or destroy resources in Simplefunctions. 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 cancel_intent in a loop, permanently destroying resources in Simplefunctions. 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 cancel_intent 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.
Cancel an active intent. Stops trigger evaluation and prevents execution.. It is categorised as a Destructive tool in the Simplefunctions MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Simplefunctions MCP server in PolicyLayer and add a rule for cancel_intent: 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 Simplefunctions. Nothing to install.
cancel_intent 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 cancel_intent 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 cancel_intent. 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.
cancel_intent is provided by the Simplefunctions MCP server (@spfunctions/cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
