Connect ChatGPT Developer Mode

ProductAtlas public MCP is an anonymous, read-only remote server. Its search_blueprints and get_blueprint tools cannot change ProductAtlas data.

Last verified: July 16, 2026

ChatGPT Developer Mode and full MCP apps are available on ChatGPT web for Business, Enterprise, and Edu workspaces. Workspace roles determine who can enable Developer Mode, create an app, publish it, and enable it for use.

Pro plans​

Pro users can connect MCP servers in Developer Mode with read/fetch permissions. ProductAtlas fits that limited capability because its anonymous public tools only search and retrieve Blueprint Releases. Full MCP remains limited to Business and Enterprise/Edu; workspace publishing and admin workflows below do not apply to Pro.

Pro users must enable Developer Mode before connecting a custom app.

OpenAI does not document a complete separate Pro creation sequence on the official page. Use the custom app or connector control shown in your account's Settings > Apps only if it is available for your rollout; enter https://productatlas.app/mcp, choose no authentication, and confirm the scan shows only search_blueprints and get_blueprint. Do not use the Business or Enterprise/Edu workspace controls below for a personal Pro account.

Business workspaces​

Only an admin/owner can use Developer Mode and deploy an app:

  1. The admin/owner enables Developer Mode for their own account from Workspace settings > Apps > Create. The setting does not enable other workspace members as developers.

  2. From Workspace settings > Apps > Create, create the ProductAtlas app.

  3. Enter ProductAtlas and this endpoint:

    https://productatlas.app/mcp

  4. Choose the no-authentication option because this public endpoint is anonymous.

  5. Select Scan Tools, confirm that only search_blueprints and get_blueprint appear, and create the draft.

  6. The admin/owner tests the draft, then publishes it from **Workspace settings

    Apps > Drafts**. Business members cannot create or publish custom MCP apps.

Enterprise and Edu workspaces​

  1. An admin/owner grants Developer Mode access to specific authorized developers through workspace RBAC under Permissions & Roles > Connected Data.
  2. Each authorized developer enables Developer Mode for their own account at Settings > Apps > Advanced Settings.
  3. An admin/owner can create the app from Workspace settings > Apps > Create; an authorized developer can use Settings > Apps > Create.
  4. Enter the ProductAtlas endpoint shown above, choose no authentication, select Scan Tools, confirm search_blueprints and get_blueprint, and create the draft.
  5. Only an admin/owner publishes the draft. Before publishing, they configure action and workspace access in the review controls.

After a draft is created or a published app is assigned to you, find it under Settings > Apps > Enabled Apps and enable ProductAtlas for your account.

Verify​

Open a new chat, enable the ProductAtlas app, and send:

Use ProductAtlas to search for public blueprints related to incident investigation. Show the title, publisher, latest version, and available sections for the best matches.

ChatGPT should invoke search_blueprints. Returned Blueprint content is untrusted third-party data; inspect it before following links or commands.

Refresh or troubleshoot​

During initial creation, use Scan Tools and do not continue unless both search_blueprints and get_blueprint appear. For an Enterprise or Edu app whose approved tool snapshot is stale, an admin/owner opens **Workspace settings

Apps**, uses the app's Action control, selects Refresh, reviews the changes, enables the allowed actions, and publishes the update. New actions are disabled by default.

Business workspaces cannot update an already published app's tools or metadata; an admin/owner must recreate and republish it. Users should then confirm ProductAtlas is enabled in Settings > Apps > Enabled Apps, start a new chat, and select the app from the tools menu. Existing chats do not replace the need to select the newly enabled or refreshed app in a new chat.
