Why connect Google Ads to Codex?

Codex runs in your terminal, its IDE extension and scripts, so what it finds once can be rerun with codex exec instead of redone by hand. Connected through Lemonado, it reads your Google Ads campaigns, search terms, PMax and budgets, so it can see what brand search really costs with today's numbers.

  • Your whole Google Ads account

    Campaigns, ad groups, ads and assets, ready to ask about.

  • Always today's numbers

    Performance Max asset groups, synced from Google Ads automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "What's our real ROAS?" use Google Ads and Meta Ads, GA4 at once.

    Ask Codex about Google Ads

    Run codex mcp list, or /mcp inside Codex, to see the server and its tools. Try "Pull last week's Google Ads numbers, save them to data/google-weekly.csv and give me the codex exec command to refresh it." Or ask: "Which terms keep wasting spend?" or "Do our UTMs match?"

What can Codex do with Google Ads?

Codex reads your Google Ads data from your terminal and turns one-off questions into commands you can rerun with codex exec.

Codex logoCodex

Pull last week's Google Ads numbers, save them to data/google-weekly.csv and give me the codex exec command to refresh it.

Saved data/google-weekly.csv. Run the same prompt with codex exec in a scheduled job and the file refreshes with each week's numbers.

# Connect Google Ads to Codex (Lemonado MCP)

- Server URL: https://mcp.lemonado.io/mcp
- Transport: Streamable HTTP
- Auth: OAuth; the user signs in to Lemonado in the browser. No API keys.
- In Lemonado: connect the Google Ads account. If you use a manager (MCC) account, choose the client accounts you want, not only the manager.
- In Codex: ~/.codex/config.toml

```toml
[mcp_servers.lemonado]
url = "https://mcp.lemonado.io/mcp"
```

If you are Codex, run the setup yourself:

Add the Lemonado MCP server to my Codex config. Append this to ~/.codex/config.toml:
[mcp_servers.lemonado]
url = "https://mcp.lemonado.io/mcp"
Then run codex mcp login lemonado so I can sign in, and check that codex mcp list shows it. Once I've signed in, list the Google Ads accounts Lemonado can reach.

First question to try: "Pull last week's Google Ads numbers, save them to data/google-weekly.csv and give me the codex exec command to refresh it."

FAQ

Frequently Asked Questions

Yes, through Lemonado. Connect your Google Ads account in Lemonado, add Lemonado in ~/.codex/config.toml, and Codex can see what brand search really costs with your live data.

You can. Google publishes an open-source Google Ads MCP server (googleads/google-ads-mcp on GitHub). It's free and read-only, but it runs locally or on your own Cloud Run and needs a Google Cloud project with OAuth credentials. In Codex that means setting up the Cloud project, credentials and Python yourself. Lemonado is one URL with a normal Google sign-in, and also covers your other channels.

Run codex mcp list. If lemonado shows as not logged in, run codex mcp login lemonado again. In Lemonado, check that Google Ads is connected and External tools is on for the company. If you sign in with a manager (MCC) account, ask about a client account by name: the data sits in the client accounts, not the manager.

Yes, if both are connected in Lemonado. One connection reaches every source you allow, so you can ask things like "Put Google Ads spend next to Stripe revenue by week for the last quarter."

MCP is included in Lemonado's paid plans and in the free trial, so you can try it before you pay.
