Objective

Detect regressions early and surface root-cause candidates before spend is wasted.

Workflow

  • •Detect anomalies on spend, clicks, impressions, CTR, CPC, conversions, CVR, CPA.
  • •Break anomalies by campaign, ad group, keyword, device where available.
  • •Produce ranked incident list with likely causes and next actions.

Core MCP Tools

  • •run_gaql_query
  • •list_campaigns
  • •list_ad_groups
  • •list_keywords
  • •get_change_history

Expected Outputs

  • •Anomaly incident list sorted by financial impact
  • •Diagnostic cuts by device/query/ad-group
  • •Immediate actions to test

Guardrails

  • •Ignore low-volume noise by minimum data thresholds.
  • •Do not auto-apply bid or budget changes from anomaly signal alone.
  • •Always include confidence level.
