Use this procedure to add Transitive to ChatGPT on the web. ChatGPT calls a connection to a custom MCP server a plugin. After you add it, you can use it in ChatGPT on other devices.

​
Before you start

  • The Transitive team must enable the service for your organization. Refer to Use an AI assistant.
  • You need the server URL: https://mcp.transitive.app/mcp.
  • On a Business plan, only a workspace admin or owner can add a custom MCP server. On an Enterprise or Edu plan, an admin must give you the permission Create plugins with MCPs in Workspace settings > Permissions & roles.
  • Menu names can change. If you do not find an item, look for the closest name.
