ChatGPT connects to Hyperspell through its custom connectors, which live behind a setting called developer mode. Once set up, ChatGPT can search the brain and ask it questions in any chat where the connector is enabled. You sign in with your Hyperspell account, so ChatGPT sees exactly what you are allowed to see.
ChatGPT support is rolling out. It depends on connector registration that we are enabling for organizations in stages. If the sign-in step does not complete for you yet, use the Claude connector or an MCP client in the meantime, and check back shortly.

​
Before you start

  • Custom connectors require a paid ChatGPT plan. Plus and Pro plans get read-only connectors, which is all Hyperspell needs for asking questions. Business, Enterprise, and Edu plans get full access.
  • On Business and Enterprise plans, a workspace admin has to allow custom MCP connectors before members can see the option. This is under Workspace settings, then Permissions and roles.
  • Copy your MCP URL from the dashboard under Settings, Connect Agents, ChatGPT. For most organizations it is https://api.hyperspell.com/mcp, and accounts in the EU region use https://api.eu.hyperspell.com/mcp. Organizations on a dedicated Hyperspell instance have their own URL, which is why copying it from the dashboard is the safe choice.

Connect ChatGPT

1

Turn on developer mode

In ChatGPT, open Settings and turn on developer mode. On a personal plan this is under your own settings. On Business and Enterprise plans it appears only after your workspace admin has allowed custom connectors.

Enabling developer mode

2

Create the connector

Open Settings, then Connectors. On some plans this section is called Apps. Create a new connector, give it a name such as Hyperspell, and paste the MCP URL.

Adding the Hyperspell connector

3

Sign in with Hyperspell

ChatGPT opens a Hyperspell sign-in page. Sign in with your Hyperspell account and approve the connection.
4

Enable it in a chat

In each new chat, open the plus menu, choose developer mode, and turn on the Hyperspell connector. A connector that is installed but not enabled for the conversation is never called. This is the usual reason ChatGPT seems to ignore Hyperspell.

Enabling the connector in a conversation

​
Using Hyperspell in ChatGPT

With the connector enabled, ask questions in plain language:
  • “What is the current status of the Acme renewal?”
  • “Find the latest version of our onboarding checklist.”
  • “Who worked on the data export feature, and what is left to do?”
ChatGPT calls Hyperspell when it decides the question needs company context, and shows which tool it used. Answers include citations you can follow back to the source documents in the dashboard.

​
Troubleshooting

I cannot find developer mode or connectors. OpenAI moves these settings between releases and gates them by plan. Check that you are on a paid plan and, on Business or Enterprise, that your admin has allowed custom MCP connectors. ChatGPT does not call Hyperspell. Open the plus menu in the chat and confirm the connector is enabled for that conversation. It has to be turned on per chat. The sign-in step fails. ChatGPT support is still rolling out, and the sign-in may not complete for every organization yet. Use the Claude connector or an MCP client for now, or contact us. Answers miss things I know are in a tool. Check in the dashboard that the tool is connected and has synced. ChatGPT only sees what your account can see.
