AI agents may call cancel-all to permanently remove or destroy resources in PraisonAI. 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-all in a loop, permanently destroying resources in PraisonAI. 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.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so cancel-all only ever does what you allow.

What does the cancel-all tool do? +

Cancel all pending requests. It is categorised as a Destructive tool in the PraisonAI MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on cancel-all? +

Register the PraisonAI MCP server in PolicyLayer and add a rule for cancel-all: 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 PraisonAI. Nothing to install.

What risk level is cancel-all? +

cancel-all is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit cancel-all? +

Yes. Add a rate_limit block to the cancel-all 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.

How do I block cancel-all completely? +

Set action: deny in the PolicyLayer policy for cancel-all. 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.

What MCP server provides cancel-all? +

cancel-all is provided by the PraisonAI MCP server (pypi:praisonai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every PraisonAI tool call.
