Set up ChatGPT with Remote MCP Private Preview

You can connect ChatGPT to Atlan's Remote MCP server to enable metadata access, search, lineage exploration, and glossary management, directly from ChatGPT. This integration leverages the MCP Developer Mode to register Atlan as a custom connector.

Prerequisites​

Before you begin, make sure you have:

  • An Atlan tenant with Remote MCP enabled. Contact Atlan support or your Atlan customer team if you don't have access.

  • Access to ChatGPT (Developer Mode). Developer Mode is available to Plus, Pro, and Enterprise users. If you don’t see this option your account or workspace may not yet support it, see OpenAI’s documentation for more information.

  • Administrator privileges to configure connectors in your ChatGPT workspace.

Enable developer mode​

Developer Mode enables you to add custom connectors and integrate ChatGPT with external MCP servers like Atlan.

  1. Open ChatGPT and go to Settings → Apps & Connectors → Advanced settings.

  2. Toggle Developer Mode to ON.

  3. When prompted with the warning message, proceed to confirm it:

    Allows you to add unverified connectors that could modify or erase data permanently.
note

Memory is automatically disabled when Developer Mode is enabled.

Set up connector​

You can connect ChatGPT to the Atlan Remote MCP server using OAuth authentication. This enables users to log in with their Atlan account and automatically use their existing roles and permissions. API Key authentication isn't supported for ChatGPT connectors.

  1. In ChatGPT, go to Settings → Apps & Connectors → Add new connector.

  2. Enter the connector name and description. For example:

    Atlan Metadata Assistant

  3. Add the MCP Server URL. This is your Atlan tenant’s Remote MCP endpoint:

    https://<your-tenant>.atlan.com/mcp

    Replace <your-tenant> with your Atlan tenant URL.

  4. Set the Authentication mode to OAuth, and select I trust this application to confirm.

  5. Click Create to add the connector. Complete the OAuth login flow to authenticate, once authentication is successful, the connector is ready to use.

  6. You can now use Atlan MCP tools directly in the chat interface. For more information, see the list of Atlan MCP tools. For example, If you want to explore lineage, write prompt like:

    show downstream assets for DIM_CUSTOMER

Troubleshooting​

  • If OAuth authentication fails, try logging out and logging back in to refresh your session.
  • If you have any issues while configuring the integration, contact Atlan Support for assistance.
