WHEN AI AGENTS USE THIS TOOL

AI agents may call delete_pki_role to permanently remove or destroy resources in HashiCorp Vault. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

WHY ENFORCE A POLICY ON DELETE_PKI_ROLE

Without a policy, an AI agent could call delete_pki_role in a loop, permanently destroying resources in HashiCorp Vault. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

hashicorp-vault.yaml 
tools:
  delete_pki_role:
    rules:
      - action: deny
        reason: "Blocked by default — enable with approval"
