Connect ChatGPT

Add Terno AI to ChatGPT as a custom MCP server.

Use Terno from ChatGPT. Once added, ChatGPT can query your Terno data sources in your conversations.

Server URL: https://mcp.terno.ai/mcp

Preview server URL: https://mcp.terno.ai/mcp/preview (adds app connectors such as Google Ads and GA4)

Before you start

Section titled “Before you start”
  • ChatGPT on the web. Your workspace’s permissions and security settings may limit who can add MCP servers.
  • A Terno AI account. You don’t need to sign up first: when you connect, Terno takes you to sign up if you don’t have an account, or to sign in if you’re signed out, and then shows the consent screen.
  • No data source is needed to connect. Ask your assistant to connect one and Terno gives it a link where you add the connection details in Terno. You can also add one in the app; see Connectors.

Connect Terno

Section titled “Connect Terno”
  1. In ChatGPT, open Plugins, select +, then Add custom MCP server.
  2. Name it Terno. In the Connection section, paste https://mcp.terno.ai/mcp (or https://mcp.terno.ai/mcp/preview for the preview server) as the Server URL.
  3. Choose OAuth. Read the warning and click I understand and want to continue.
  4. Select Create as a plugin and sign in to Terno.

Check it works

Section titled “Check it works”

Ask your assistant something like:

  • “Which data sources do I have in Terno?”
  • “Using Terno, show the top 10 customers by revenue this year.”

It should call Terno’s tools and answer from your data.

App connectors (preview)

Section titled “App connectors (preview)”

The main server works with your databases and warehouses. To also use app connectors such as Google Ads and GA4, add the preview server in the same way, using https://mcp.terno.ai/mcp/preview. It will come to the main server soon.

Troubleshooting

Section titled “Troubleshooting”
The sign-in window doesn’t open, or sign-in fails

Complete the sign-in in the browser window or tab your assistant opens, using your Terno account. If it times out, start the connection again.

Terno’s tools don’t show up

Check the server URL is exactly https://mcp.terno.ai/mcp (or https://mcp.terno.ai/mcp/preview for the preview server), and that the Terno server is switched on in your assistant.

”No data sources” or empty answers

Connect a data source in Terno first. The assistant only sees what’s connected in your Terno workspace, within your access rules.

Disconnect

Section titled “Disconnect”

Remove the Terno connector or server in your assistant.
