Explained
Many Google Ads MCP servers either expose a GAQL tool directly or build GAQL queries behind friendlier tools. Google's official Google Ads MCP server is built around running GAQL.
MegaMCP offers both: purpose-built tools for common reports and a read-only google_ads_query tool that runs one GAQL SELECT against an allowlist of resources.
