Connecting Google Ads to ChatGPT

Before you start

You'll need a SourcetoMCP account with at least one brand created, a Google account with access to at least one Google Ads account, and a ChatGPT plan that supports connectors (this can sit behind a developer mode toggle depending on your plan).

1. Connect Google Ads to SourcetoMCP

1. 1From your dashboard, go to Connectors → Add a connection.
2. 2Find the Google Ads card and select Connect.
3. 3Sign in with the Google account that has access to the account you want. This opens Google's own consent screen, not a SourcetoMCP form, and asks you to approve access to your Google Ads data — this covers both reading performance data and making changes on your behalf, since SourcetoMCP can do both.
4. 4Back in SourcetoMCP, choose which account(s) to connect — each one shows up with its real name and customer ID (e.g. “Acme Co (624-809-0961)”) — then confirm. They show up on your Connections page.

2. Add SourcetoMCP as a connector in ChatGPT

1. 1In SourcetoMCP, open Connect an agent from the dashboard sidebar and copy your server address (it looks like https://sourcetomcp.com/api/mcp).
2. 2In ChatGPT, click Plugins in the sidebar menu.
3. 3Click the “+” sign in the plugins menu.
4. 4Enter the name SourcetoMCP and paste your server address into the connection's server URL field.
5. 5Tick the option and click Create.
6. 6The first time ChatGPT uses it, you'll be asked to sign in to SourcetoMCP and approve access, the same OAuth approval you'd see connecting any other app. After that it reconnects automatically.

Once approved, the connection appears under Active connections on the Connect an agent page in SourcetoMCP, so you can see exactly what has access at any time.

3. Ask ChatGPT about your Google Ads account

With both pieces connected, ChatGPT can query campaign, ad group and keyword performance, dig into search terms, check Quality Score, and review Google's own recommendations — and, if you ask, act on what it finds. Try something like:

1. 1How did my Search campaigns perform last week compared to the week before?
2. 2Show me search terms that got clicks but no conversions in the last 30 days.
3. 3What's dragging down my Quality Score in my worst-performing ad groups?
4. 4Find negative keyword candidates from my worst-performing search terms and add them.

The first three are read-only reports. The last one is a write action — see the note below on how SourcetoMCP handles those.

A note on write actions

Unlike a read-only connector, Google Ads through SourcetoMCP can create and change real things in your account — campaigns, ad groups, keywords, budgets, negative keywords and more. New campaigns and ad groups are created paused by default, so nothing starts spending without an explicit follow-up action, and ChatGPT will tell you what it's about to change before it does anything irreversible. Worth reading its proposed action before confirming, the same as you would for any assistant with write access to a live ad account.

Troubleshooting

My account isn't in the list when connecting: the signed-in Google account doesn't have access to that Google Ads account. Add it under Google Ads' own Tools & Settings → Access and security, then reconnect.

ChatGPT doesn't show a Plugins option: this feature rolls out by plan. Check ChatGPT's own settings or plan details if you don't see it.

ChatGPT says it can't find the tool or has no data: reopen the connector in ChatGPT's Settings and confirm it still shows as connected; if not, remove and re-add it to trigger a fresh approval.

Revoking access

You can disconnect from either side. In SourcetoMCP, remove the account from your Connections page, or revoke ChatGPT's access entirely from the Connect an agent page. In ChatGPT, remove the connector from the Plugins menu.
