WHAT IT DOES

What unsubscribe_webhook does on instantKOM MCP Server

AI agents call unsubscribe_webhook to permanently remove resources in instantKOM MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why unsubscribe_webhook is rated Critical

The tool irreversibly deletes a webhook subscription, which is a configuration that cannot be restored without manual intervention. Deletion of integrations/webhooks can break critical notification and event-driven workflows, causing service disruption. This qualifies as Destructive rather than Write because the action is deletion-based and cannot be easily undone.

From the tool's definition Tool name 'unsubscribe_webhook' and description 'Delete a webhook subscription by ID' explicitly specify deletion of a webhook resource.

unsubscribe_webhook Hidden
