Connect your marketing data to ChatGPT: the whole setup

Written by Uptimal, the team that builds and operates Upbuild and runs marketing analytics for multinational clients across the globe. Everything below reflects how the connector actually behaves in production.

ChatGPT becomes a marketing analyst the moment it can call your platforms as tools. This is the umbrella setup: one plugin, the whole stack, current for the 2026 plugin era.

The ChatGPT path

ChatGPT needs Developer mode first: Settings, Security and login, switch on Developer mode. Then Settings, Plugins, Browse plugins, hit the + button and fill the New Plugin dialog: name Upbuild, Connection on Server URL with https://connector.upbuild.app/mcp, Authentication OAuth, tick the custom-server notice, Create. The setup guide shows every screen.

Then stack the platforms

The first Google OAuth covers Google Ads, GA4, GTM, CM360 and DV360. The connect hub then links Meta, TikTok, Snapchat and Adobe, each with its own read-only consent.

Prove it in the first ten minutes

• “List the ad accounts and GA4 properties you can see.” (Sanity check of scopes.)
• “Blended spend and ROAS by platform, this month.”
• “Which platform’s CPA moved most week over week, and show the campaign behind it.”

Security posture in one line: per-user OAuth, read-only scopes, encrypted tokens, disconnect kills access; the long version is in the security explainer.
