Remove keywords from ad groups.
AI agents call google_ads_remove_keywords to permanently remove resources in Google Ads MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing keywords from ad groups is a destructive action: once removed, the keywords stop serving and their configuration is lost. This can immediately impact campaign performance and ad delivery, representing a high blast radius if misused by an AI agent. Financial impact is indirect (no money movement), but the irreversible nature of keyword removal places this in the Destructive category.
From the tool's definition 'Remove keywords from ad groups' — removal is irreversible in operational terms; deleted keywords and their associated historical data/configurations cannot be automatically restored.
