AI agents may call revoke_delegation to permanently remove or destroy resources in Agent Passport System — Cryptographic Identity for AI Agents. 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 revoke_delegation in a loop, permanently destroying resources in Agent Passport System — Cryptographic Identity for AI Agents. 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.

[OPERATOR] Revoke a delegation. Optionally cascade to all sub-delegations.. It is categorised as a Destructive tool in the Agent Passport System — Cryptographic Identity for AI Agents MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Agent Passport System — Cryptographic Identity for AI Agents MCP server in PolicyLayer and add a rule for revoke_delegation: 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 Agent Passport System — Cryptographic Identity for AI Agents. Nothing to install.
