Connect Quentn to ChatGPT
The interface may change during the beta. The terminology below reflects the interface as of September 1, 2026.
- Open Settings in ChatGPT.
- Open Apps, then go to Advanced Settings or the section for creating custom MCP apps.
- Enable Developer Mode if it is available for your account and is not already enabled.
- Select Create app or Add custom app.
- Enter Quentn (Beta) as the name.
- Enter https://mcp.quentn.com/mcp as the MCP server URL.
- Save the app and start Connect or the authentication process.
- Sign in to Quentn, select the system you want to use, and confirm access.
- Open a new chat, enable the Quentn app, and begin with a read-only or preview request.
Business, Enterprise, or Edu workspaces may require approval from an admin or owner. According to current OpenAI documentation, full MCP functionality, including write actions, is limited to Business and Enterprise/Edu plans. Pro users can use custom MCP connections in Developer Mode only with read/fetch permissions. If certain actions are unavailable, first check your plan, workspace role, and app permissions.
