🚧 Prototype

The Dataddo MCP server is an early prototype. See the Dataddo MCP Server overview for its current capabilities and roadmap.

Connect the Dataddo MCP server to ChatGPT as a custom connector using ChatGPT's developer mode.

⚠️ Authentication limitation

ChatGPT custom connectors support OAuth, No Authentication, and Mixed Authentication - they cannot send a static API token header. For now, connect to the Dataddo MCP server without authentication, which limits you to tools that do not access account data (such as current-time). Support for authenticated access from ChatGPT is planned.

Prerequisites

  • A ChatGPT Pro, Plus, Business, Enterprise, or Education account. Custom connectors are available on the web app only.
  • Developer mode enabled: go to Settings → Security and login and toggle Developer mode on.
  • On Business and Enterprise workspaces, a workspace admin may need to allow creating custom MCP connectors first.

Setup

  1. In ChatGPT (web), open Settings and go to the connectors/apps section.
  2. Click the + button to add a new connector.
  3. Fill in:
    • Name: Dataddo
    • MCP server URL: https://headless.dataddo.com/mcp
    • Authentication: No Authentication
  4. Confirm. Dataddo's tools appear on the connector's detail page, where you can toggle individual tools on or off.

Try It Out

Start a new chat, enable the Dataddo connector for the conversation, and ask:

Using the Dataddo tools, what is the current time in UTC?

Troubleshooting

  • The connector option is missing. Confirm your plan supports developer mode, that it is toggled on, and (for Business/Enterprise) that your workspace admin has allowed custom connectors.
  • Connection fails. Verify the URL is exactly https://headless.dataddo.com/mcp.
