WHAT IT DOES

What gcp_pubsub_delete_topic does on GCP MCP Server

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

RISK

Why gcp_pubsub_delete_topic is rated Critical

This tool performs an irreversible destructive action (deletion) on a GCP resource. Once a Pub/Sub topic is deleted, it cannot be recovered, and any messages or subscriptions associated with it are lost. The blast radius depends on the topic's criticality and how many applications depend on it, but the operation is fundamentally non-undoable, placing it in the Destructive category with high severity.

From the tool's definition Tool name explicitly includes 'delete' and description states 'Delete a Pub/Sub topic'. Deleting a topic is an irreversible operation that removes the topic and typically its associated messages and subscriptions.
