Permanently revoke and delete an API key.
AI agents call dual_delete_api_key to permanently remove resources in DUAL MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting an API key is an irreversible action that removes authentication credentials. While not as severe as financial or widely-scoped data destruction, permanent revocation of an API key cannot be undone and could disrupt services if the agent deletes the wrong key. The high confidence reflects clear destructive language in the description.
From the tool's definition Tool description explicitly states 'Permanently revoke and delete an API key' — the verb 'delete' combined with 'permanently' indicates irreversible data destruction.
Attacks that exploit this kind of access
Permanently revoke and delete an API key. It is categorised as a Destructive tool in the DUAL MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the DUAL MCP Server MCP server in PolicyLayer and add a rule for dual_delete_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 DUAL MCP Server. Nothing to install.
dual_delete_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 dual_delete_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 dual_delete_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.
dual_delete_api_key is provided by the DUAL MCP Server MCP server (ro-ro-b/dual-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
