Can AI manage several Google Ads accounts and your MCC? Yes, with one connector

With Fezola, you connect your Google account once: Claude or ChatGPT then sees every ad account it can reach, including the direct client accounts under your manager (MCC) account, and can report on all of them in one request. No spreadsheet export, no switching accounts in the Google Ads interface, nothing to install. ChatGPT accepts custom MCP servers on Business and Enterprise/Edu plans (Pro read-only), so Claude is the easiest way in.

What Fezola does with several accounts

From Fezola's tools, as read in the code:

• google_ads_list_accounts lists, in one list, the ad accounts the connected Google accounts can access directly, and the direct client accounts of the manager accounts among them. Each has its name, currency, time zone, whether it is a manager or a test account, and the Google account it comes from. Disabled accounts are left out.
• google_ads_campaign_performance reports campaigns over a period for every non-manager account at once, or for the accounts you name (up to 50), with a total per account in that account's currency. Manager accounts have no campaigns of their own, so they are skipped.
• google_ads_search runs a read-only GAQL query on one account of your choice, for anything beyond the standard report.
• google_ads_keyword_ideas gives Keyword Planner ideas on an account.

If one Google account loses access or an account fails, the others still answer: failures are listed next to the results.

Questions for an agency or freelancer

• "Compare cost, conversions and cost per conversion for all my client accounts over the last 30 days. One line per account."
• "Which accounts spent money this week with zero conversions?"
• "List my accounts that are manager accounts and which clients they hold."
• "For the account named [client], show the ten most expensive keywords over 30 days."

Limits to know

• Direct clients only. For each manager account, Fezola reads its direct client accounts. Clients that sit deeper in a nested manager tree appear only if your Google account can reach them directly.
• A cap on discovery. Fezola looks at up to the first 50 accounts a Google account can access directly, and up to 200 direct clients per manager.
• No cross-account sum. Each account keeps its own currency, with a total per account.
• Access comes from Google. An account you cannot open in Google Ads cannot be read through Fezola.

Writing on client accounts: be deliberate

Fezola can also create, edit, pause and remove items and set budgets, and writing is on by default. On a client account, that is real money and a real relationship. Habits that help:

• Ask for validate-only first: Google checks the change and applies nothing.
• Keep your assistant's approval prompts on: the writing tools are marked destructive.
• Name the account in every request, with its customer id, so a change cannot land on the wrong client.
• Remember there is no spending cap on Fezola's side, and removals cannot be undone in Google Ads.

Setup

1. Create a free Fezola account, then Sources, Add source, Google Ads, and sign in with your Google account. Repeat for other Google accounts.
2. Add Fezola to Claude with https://api.fezola.com/mcp: see how to add a custom connector to Claude, or the step-by-step Google Ads in Claude: connect your accounts.

Fezola also manages OpenAI Ads and Microsoft Advertising accounts with the same connector. If you prefer to run the server yourself, see Google Ads MCP server: hosted vs self-hosted.
