google_ads_list_keywords
AI agents call google_ads_list_keywords to retrieve information from Google Ads MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
List operations retrieve data with no side effects. While the description is uninformative (lowering confidence slightly from 0.9), the tool name is explicit: 'list' is a read-only operation. The Google Ads context (campaign management) supports that listing keywords is a standard query operation to view configured keywords, not to create, modify, or delete them.
From the tool's definition Tool name 'google_ads_list_keywords' indicates retrieval/query of keyword data. The description is empty, but the name and context of a Google Ads management server clearly suggest this lists existing keywords without modification.
