Delete a face definition.
AI agents call dual_delete_face 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.
The tool performs an irreversible deletion of a face definition, which cannot be undone. This is a destructive action on data within the DUAL Web3 Operating System. While the blast radius is primarily scoped to face definitions rather than critical financial or system infrastructure, unauthorized or accidental deletion could disrupt template management or identification workflows.
From the tool's definition Tool name explicitly includes 'delete' and description states 'Delete a face definition' — irreversible data removal operation.
Attacks that exploit this kind of access

Register the DUAL MCP Server MCP server in PolicyLayer and add a rule for dual_delete_face: 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_face 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_face 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_face. 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_face 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.
