Delete a contact.
AI agents call keyid_delete_contact to permanently remove resources in KeyID Agent Kit — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a contact is irreversible and removes data that cannot be recovered through normal API operations. While the blast radius is scoped to a single contact record (not system-wide), the permanent nature of deletion and the AI agent's potential to misidentify or recursively delete multiple contacts elevates this to Destructive rather than Write.
From the tool's definition Tool name 'keyid_delete_contact' combined with description 'Delete a contact' indicates irreversible removal of contact data. The verb 'delete' is characteristic of destructive operations.
Attacks that exploit this kind of access
Delete a contact. It is categorised as a Destructive tool in the KeyID Agent Kit MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the KeyID Agent Kit MCP server in PolicyLayer and add a rule for keyid_delete_contact: 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 KeyID Agent Kit. Nothing to install.
keyid_delete_contact 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 keyid_delete_contact 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 keyid_delete_contact. 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.
keyid_delete_contact is provided by the KeyID Agent Kit MCP server (keyid-ai/agent-kit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
keyid_delete_contact is one line of KeyID Agent Kit's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
