google-ads-mcp

MCP server for Google Ads — diagnose spend efficiency, impression share, and asset performance from Claude.

22 tools across campaigns, keywords, RSAs, assets, audiences, geo/device splits, impression share, auction insights, and budget pacing — plus a raw GAQL escape hatch. Built for B2B paid search teams and agencies running real diagnosis, not just dashboard-style "list my campaigns" queries.

Why this exists

Most Google Ads MCP servers stop at "list campaigns + basic metrics." This one goes after the questions paid search teams actually ask: which RSA assets are labeled LOW so I can replace them, which keywords burn budget with zero conversions, who am I losing impression share to in auction insights, what's my mobile vs. desktop CPA gap, which campaigns are budget-limited right now. Those are the levers you pull to fix performance — and they're all first-class tools here.

Differentiated from the official googleads/google-ads-mcp: ships RSA asset performance labels, auction insights, impression share analysis, geo/device splits, audience targeting inspection, and budget pacing.

Example prompts

Once installed, ask Claude things like:

- "What's my impression share vs competitors this month? Who am I most often losing to?"
- "Show all RSA assets with LOW performance labels so I can replace them."
- "Which keywords are spending the most with zero conversions in the last 30 days?"
- "What's my mobile vs. desktop CPA difference across all campaigns?"
- "Are any campaigns budget-limited right now? Show Lost IS (Budget)."
- "List my remarketing audiences and tell me which ones are large enough to target in Search."
