AI agents may call anilist_undo to permanently remove or destroy resources in Ani. 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 anilist_undo in a loop, permanently destroying resources in Ani. 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 anilist_undo 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.
Undo the last write operation (update progress, add to list, rate, delete, or batch update). Restores the previous state of the affected list entry. Requires ANILIST_TOKEN.. It is categorised as a Destructive tool in the Ani MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ani MCP server in PolicyLayer and add a rule for anilist_undo: 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 Ani. Nothing to install.
anilist_undo 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 anilist_undo 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 anilist_undo. 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.
anilist_undo is provided by the Ani MCP server (gavxm/ani-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
