Google Ads MCP Server

An open-source server from Google that lets an assistant query Google Ads accounts for reporting and analysis.

What it is and why it matters

What it does

• Runs GAQL queries
• Lists accessible accounts
• Pulls campaign, ad group and keyword performance

Best for

Audits, reporting and anomaly checks across one or many accounts.

How to connect it

1. Get a Google Ads API developer token, which is requested from a Google Ads manager account.
2. Create OAuth credentials (or use application default credentials) that have access to the accounts you want to query.
3. Install and run the server on your computer as described in the project's README on GitHub.
4. Add the server to your AI tool's MCP settings, then provide the customer ID of the account, and the manager account ID if you work through one.
5. Start with a simple question, such as listing the accounts the credentials can reach, before running larger analysis.

Exact commands and addresses change. Use the official documentation for the current steps.

Questions you can ask it

• Which campaigns spent more than 20 percent of the budget last week and returned less than the account average ROAS?
• List search terms from the last 30 days with more than 50 in spend and no conversions.
• Compare conversion value and cost by campaign this month against last month and explain the biggest changes.
• Show Performance Max asset groups ordered by cost with their conversion value.

What it cannot do

• It cannot change anything: no pausing campaigns, editing bids or creating ads.
• It reports the conversion value Google Ads holds. If that value is revenue, you will get revenue-based ROAS, not profit.
• It cannot fix broken conversion tracking. Wrong or missing conversions in the account produce wrong answers.

Staying safe

• Treat the developer token and OAuth credentials like passwords and keep them out of chats and shared files.
• Use the least access that works: read access to the accounts you actually need.
• Verify any figure you will act on against the Google Ads interface before changing spend.

Watch out for: Needs a developer token and OAuth setup. Read-only means it reports on spend but cannot change it.
