Read-only MCP server for the Google Ads API. Eleven tools cover discovery, GAQL reporting, resource schema, recommendations, keyword planning and forecasts, and change history for any account reachable under a manager account (MCC). We run this server in production for every ads client. Read-only is enforced at three layers: no mutate or apply service imports, an SDK method allowlist, and a GAQL-starts-with-SELECT guard.

This is the heaviest setup in the gallery: expect up to two days waiting on developer token approval. One set of credentials, rooted at a manager account (MCC), can read any customer account linked under it, so there is no per-client configuration beyond linking an account to the MCC.
https://www.googleapis.com/auth/adwords scope to the OAuth consent screen.oauth2l tool or the generate_user_credentials.py example shipped with the google-ads Python library. Save the refresh token; it does not expire from normal use.GOOGLE_ADS_LOGIN_CUSTOMER_ID. Any client account accepts an invite to link under this manager account in its own Google Ads UI, after which google_ads_list_customer_clients sees it.| Tool | What it does |
|---|---|
google_ads_list_accessible_customers | List every customer_id the OAuth user has direct access to |
google_ads_list_customer_clients | Walk the MCC hierarchy and return every child account |
google_ads_query | Run a GAQL query against a specific customer account |
google_ads_describe_resource | Schema (fields, metrics, segments) for a GAQL resource |
google_ads_list_resources | Return the full catalog of GAQL resources |
google_ads_recommendations | Read Google's optimization recommendations for a customer account |
google_ads_keyword_ideas | Generate keyword ideas with search volume, competition and CPC estimates |
google_ads_keyword_historical_metrics | Historical monthly search-volume and competition metrics for specific keywords |
google_ads_keyword_forecast_metrics | Forecast KPIs for a proposed keyword plan |
google_ads_change_events | Audit trail of who changed what, last 30 days |
google_ads_change_status | Lightweight last-modified change tracker per resource |
| Variable | Required | Purpose |
|---|---|---|
GOOGLE_ADS_DEVELOPER_TOKEN | yes | Google Ads API developer token from the Ads API Center |
GOOGLE_ADS_CLIENT_ID | yes | OAuth2 client_id for a Desktop-app credential |
GOOGLE_ADS_CLIENT_SECRET | yes | OAuth2 client_secret paired with the client_id |
GOOGLE_ADS_REFRESH_TOKEN | yes | Long-lived OAuth2 refresh_token for the adwords scope |
GOOGLE_ADS_LOGIN_CUSTOMER_ID | yes | 10-digit customer ID of the manager account (MCC), no hyphens |
GOOGLE_ADS_API_VERSION | no | Google Ads API version to target, default v25 |
GOOGLE_ADS_USE_PROTO_PLUS | no | Use proto-plus message types, default true |
GOOGLE_ADS_LOG_LEVEL | no | Python log level, default WARNING |
Every tool returns JSON with status (succeeded, partial, no_op), operation, summary, target, result, proof, warnings, recovery. Failures surface as a tool error whose text is google_ads_request_failed: <message> <hint>. proof.apiVersion names the Google Ads API version used. proof.microsConverted is set on google_ads_query. A partial status means the result hit its configured bound (max_rows, page_size or limit); recovery.nextAction says how to continue.
google_ads_query responses are capped at 64 MB per call by the Google Ads API; split large date ranges across calls. KeywordPlanIdeaService (keyword ideas, historical metrics, forecasts) is rate-limited to 1 query per second and may require Basic Access if you get a permission error on the Explorer tier. google_ads_change_events covers up to 30 days back; google_ads_change_status covers up to 14 days back. metrics.cost_micros and other *_micros fields are 1 unit = $0.000001; google_ads_query emits a matching *_units field alongside when convert_micros is true (the default).
Each release lists the package version, the .mcpb sha256 and the production commit it was derived from in CHANGELOG.md. CI runs the tests and a clean install of the built wheel on every push.
