AI agents may call apikeys_rotate_api_key to permanently remove or destroy resources in DataNexus MCP. 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 apikeys_rotate_api_key in a loop, permanently destroying resources in DataNexus MCP. 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 apikeys_rotate_api_key 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.
Revoke the current API key and issue a replacement. Returns the new key once — store it immediately. Pass keys as the X-DataNexus-Key header.. It is categorised as a Destructive tool in the DataNexus MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the DataNexus MCP server in PolicyLayer and add a rule for apikeys_rotate_api_key: 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 DataNexus MCP. Nothing to install.
apikeys_rotate_api_key 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 apikeys_rotate_api_key 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 apikeys_rotate_api_key. 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.
apikeys_rotate_api_key is provided by the DataNexus MCP server (dev-7bd0/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
