Upbuild
Upbuild / MCP connector / ChatGPT
Upbuild connector · ChatGPT
Paste one server URL into ChatGPT and ask your Google Ads, Meta, TikTok, GA4 and Adobe accounts anything, in the chat your team already keeps open. Read-only, on your own logins. It needs a paid ChatGPT plan with Developer mode switched on.
Every platform on one subscription
Before you start
ChatGPT keeps custom MCP servers behind Developer mode, so the first two minutes belong to ChatGPT, not to us. You need Plus, Pro, Business, Enterprise or Edu, you have to do it in the web app, and on Business and Enterprise a workspace admin may have to allow it before the switch appears at all. After that it is one dialog: a name, a URL, and OAuth. If you would rather follow one platform end to end, there is a walkthrough for Google Ads and one for GA4.
Developer mode lives under Settings, then Security and login. If the switch is not there, the plan is free or the workspace has not allowed custom plugins. Nothing on the Upbuild side can change either of those.
ChatGPT shows a warning and asks you to tick "I understand and want to continue" for every custom MCP server, Upbuild included. It is a platform-wide notice, not a judgement on the server you are adding.
Settings, then Plugins, then the plus button next to the plugin search box.
In the chat
Once Upbuild is switched on in a chat's tools menu, ChatGPT reads every account your Google login already reaches, across every platform on one subscription. It queries the platform APIs on the spot, so the figures are the platform's own rather than a copy sitting in a middle layer, and a question about last month can be asked at 11pm the day the month ends.
Spend from Google Ads, results from Meta and sessions from GA4 can land in a single table, because the assistant calls each platform's tools inside the same turn.
All 80 tools only fetch. Nothing pauses a campaign, moves a budget or writes a row, and every teammate connects with their own login, so nobody inherits access they did not already have.
Upbuild sits in the tools menu of the chat. Ask, and it reads what your Google login can see.

ChatGPT or Claude
It is one server either way: the same 80 tools, the same read-only rules, the same Google sign-in, the same platforms. Only the way in differs, and it is fair to say Claude is the easier door, because Upbuild sits in the Claude connector directory as one click on every Claude plan. ChatGPT asks for a paid plan and a settings toggle first, and in return puts the data in the assistant most organisations have already standardised on.
It is the assistant already rolled out across the company, with the workspace controls IT wanted, and its scheduled Tasks can re-run a saved prompt on a clock instead of someone retyping it every Monday.
Add Upbuild in Claude and in ChatGPT on the same Google login and that is two seats. Reconnecting the same assistant as often as you like is still one.
What ChatGPT connects to is exactly what Claude, Copilot Studio and Gemini Enterprise connect to.
Setup, end to end
This is the whole procedure, in the order ChatGPT puts it in. The setup guide has the same steps with the dialog rebuilt field by field, plus the second and third Google logins agencies use, and the connector overview covers what it can reach once it is in.
In ChatGPT on the web, go to Settings, then Security and login, and switch on Developer mode. This needs a paid plan: Plus, Pro, Business, Enterprise or Edu. On Business and Enterprise a workspace admin may have to allow custom plugins first.
Go to Settings, then Plugins, and click the plus button next to the plugin search box. Name it Upbuild, leave Connection on Server URL, paste https://connector.upbuild.app/mcp, set Authentication to OAuth, tick the custom-server notice and click Create. Skip the icon.
Click Connect and authorise the Google account that already has access to your platforms. The hub then offers Meta, TikTok and Snapchat with one click each; Adobe Analytics and Adobe Launch take a one-time credential setup of about ten minutes. Open a chat, check Upbuild is on in the tools menu, ask.
Prompts
Written for a portfolio rather than a single account. Each one reads live from the platform, and each one is read-only, so it is safe to run on a client account in the middle of the day.
"Summarize last month across Google Ads and Meta: spend, conversions, ROAS, top 5 campaigns." It calls gads_campaign_performance and meta_insights in the same turn and comes back with one table instead of two exports.
"Every weekday at 9:00, pull yesterday's Google Ads and Meta spend, conversions and ROAS, compare them with the seven-day average and give me the three biggest movers." Save it as a ChatGPT Task and the prompt re-runs on its own clock.
"Compare GA4 sessions and conversions with Google Ads clicks and conversions for last month by campaign, and list the ten with the biggest gap." The question everyone asks the day before a client call, written up in full in the ChatGPT reporting guide.
"For every Google Ads account I can reach, list the campaigns whose spend moved more than 20 percent week on week." One organisation in Upbuild today reaches 859 accounts. That is the question nobody does by hand twice.
If something looks off
Three of them are ChatGPT settings and one of them is platform access. None of them needs a support ticket.
Developer mode is off, the plan is free, or a workspace admin has not allowed custom plugins. Check Settings, then Security and login, in ChatGPT on the web, which is where the switch lives.
Nothing to repair by hand. The next tool call prompts you to sign in again, and changes to what your login can reach are picked up on their own. TikTok is the one platform that asks for a fresh authorisation on a schedule, every 30 days, by TikTok's own design.
Upbuild only surfaces accounts your Google or Meta login already reaches. Get access granted on the platform itself, in Google Ads or in Business Manager, then ask the same question again.
Ask ChatGPT to run whoami. It returns the Google identity behind the connection along with your subscription and trial state. For plans and cancellation, ask for manage_billing. More answers on the setup page.
