AdChat vs Google's Official Google Ads MCP (2026)

The quick answer: Google's official Google Ads MCP server is free, open source and first-party, but you run it yourself on a Google Cloud project, and it can't change campaigns, ads, keywords or budgets. AdChat is hosted: you sign in with Google, paste one URL, and your AI app can pause things, change budgets, add keywords and negatives and draft new ads, with a yes before anything that spends money. If you only need reports and know Google Cloud, use Google's. If you want changes, Meta in the same place, or no setup, use AdChat.

Key takeaways

• Google's server is a developer tool. It needs a Cloud project with Explorer access or higher, Python 3.10+, pipx and the gcloud CLI. Our estimate: 30 to 60 minutes the first time if you've never used Google Cloud.
• It reads almost everything, and writes very little. GAQL can query any report. Writes are limited to standalone assets and labels; Google says it can't touch campaigns, ad groups, ads, budgets or bids.
• AdChat takes about two minutes. No developer token, no Cloud project, nothing to install. It works in Claude, ChatGPT, Grok, Cursor, Codex and Claude Code.
• AdChat changes things, carefully. Spend rules, Google's check-only mode, paused-by-default ads, a log and an undo. It can't create new campaigns.
• Run Meta too? AdChat answers for both from the same address. Try it free for 7 days, no card.

We make AdChat, so discount our view accordingly. Facts about Google's server come from its developer guide and GitHub README, checked November 13, 2026. Google is adding tools quickly, so check its release notes before you decide.

Side by side

Checked November 2026.

When Google's official server wins

• You only need reports. GAQL reaches fields no hosted tool exposes, and it costs nothing.
• No third party allowed. Your data goes from Google to your machine and your AI app, nobody else.
• You already have a Cloud project with Explorer, Basic or Standard access.
• You work in Gemini CLI or Antigravity, where Google documents the setup first.
• You want labels or bulk asset creation, which AdChat doesn't do.

Where AdChat wins

• It can change your account. Pause a wasteful keyword, add negatives from your search terms, raise a budget, draft a new ad. Google's server sends you to the Google Ads interface for all of that.
• No Cloud project. Nothing to install, upgrade or keep running.
• Google and Meta in one answer. Ask "where did my ad budget work best last week?" and get both platforms side by side.
• Built for people who aren't developers. Plain-English answers, and a yes before anything that spends money, goes live or can't be undone. You can set an account to ask before every change.

Setup, step by step

Google's official server (local, per Google's guide)

1. Create a Google Cloud project and enable the Google Ads API. This gives you Test access, which only works with test accounts. (About 5 minutes.)
2. Apply for Explorer access on the Google Ads API Overview page. Google says it reviews this automatically in most cases. (Usually quick, but Google gives no time.)
3. Create an OAuth client and download its JSON file. (About 5 minutes.)
4. Install Python 3.10+, pipx and the gcloud CLI if you don't have them. (10 to 20 minutes.)
5. Log in with gcloud auth application-default login, passing the Google Ads scope and your client file.
6. Add the server to your AI app's MCP config (pipx run google-ads-mcp, with GOOGLE_CLOUD_PROJECT set). If you reach accounts through a manager account, also set GOOGLE_ADS_LOGIN_CUSTOMER_ID.
7. Restart your AI app and ask a question.

Want it in Claude or ChatGPT on the web? Add a Cloud Run deployment with Secret Manager and an OAuth web client. Google's guide warns never to deploy it publicly without that OAuth client. The times above are our estimates; Google doesn't publish any.

AdChat

1. Sign up at adchat.app. No card. (1 minute.)
2. Connect Google. AdChat adds every Google Ads account that login can see. (30 seconds.)
3. Add https://mcp.adchat.app to your AI app (Claude, ChatGPT, Cursor) and sign in. Already using AdChat for Meta? Skip this step. (1 minute.)

Can I use both?

Yes. Keep Google's server for deep GAQL reports and add AdChat for changes and Meta. Say which one you want in your prompt:

Use AdChat to add the wasted search terms from last month as negative keywords.

FAQ

Is Google's Google Ads MCP server free?

Yes. It's open source under Apache-2.0. You pay only for hosting if you deploy it to Cloud Run. AdChat has a 7-day free trial, then $29 or $49 a month.

Can Google's official server pause campaigns or change budgets?

No. Google's guide says it can't create, modify, pause or enable campaigns, ad groups, ads, budgets or bids. Its write tools cover standalone assets and labels.

Do I need a developer token for either one?

No. Google retired developer tokens on September 9, 2026. Google's server needs a Cloud project with Explorer access instead. AdChat needs only a Google sign-in.

Does AdChat use Google's MCP server behind the scenes?

No. AdChat calls the Google Ads API directly from its own hosted server.

Can AdChat create Google Ads campaigns?

Not yet. Build the campaign in Google Ads, then use AdChat to manage it: budgets, status, keywords, negatives and new responsive search ads.

Which is safer?

Both make you confirm writes. Google's server can be locked to read-only. AdChat asks before anything that spends money, checks your spend rules and Google's check-only mode, creates ads paused, and keeps an undo for each change.
