Your ad accounts, inside ChatGPT

What you'll have at the end: ChatGPT answering from your Google Ads, Meta ads, TikTok ads, Reddit ads and X ads, and drafting the changes you allow.

Before you start

• (checked Nov 2026)
• An OpenAdManager account, or create one in the sign-in window.

Install on the web

1. Open chatgpt.com/plugins, click +, then Add custom MCP server.
2. Give it a name and a short description. Set Connection to Public endpoint and paste the URL: https://mcp.openadmanager.com/mcp
3. Sign in to OpenAdManager and click Allow. Pick the workspace and the ad accounts ChatGPT may use.
4. ChatGPT shows a risk notice. Read it, then click I understand and want to continue.
5. Click Create as a plugin, review the tool list, and start a new chat with @OpenAdManager.
6. After any change to the tool list, click Refresh in the plugin.

Install in the desktop app

Settings, MCP servers, Add server, choose Streamable HTTP, paste https://mcp.openadmanager.com/mcp, Restart, then Authenticate.

Check it worked

Use OpenAdManager: list my ad accounts.

Then: "Which of my campaigns spent the most in the last 7 days, and what did each bring in?"

Two sets of permissions

ChatGPT has its own per-app permission levels and asks you to confirm changes. OpenAdManager adds its own AI permissions: which kinds of change your AI may make, all on to start, and you can turn any off. Both apply.

If something goes wrong

• ChatGPT says it cannot make changes. That can be your ChatGPT plan, not OpenAdManager. Check the note at the top of this page.
• A tool is missing after a plan change. Click Refresh in the plugin.
• "Not done. ... is turned off in AI permissions". That is your switches working. Open the link in the message, or Add to your AI in the menu, and turn it on if you want it.
• Wrong ad account. In OpenAdManager, open Connections, then ChatGPT, then Accounts.
