ChatGPT

Add Display.dev as an MCP app in ChatGPT and authorize publishing tools.

On this page

Add Display.dev as a custom MCP app so ChatGPT can publish and update artifacts from a conversation.

Full MCP write actions are available on ChatGPT Business and Enterprise/Edu on the web. Your workspace must allow developer mode, and you must be an Admin, Owner, or authorized developer. ChatGPT Pro custom apps are limited to read and fetch actions, so they cannot run Display.dev's publishing tools.

Enable developer mode

An Admin or Owner first enables developer access for the workspace. Depending on the plan, this control is under Workspace settings → Permissions & Roles → Connected Data or Settings → Apps → Advanced Settings.

Business Admins and Owners enable developer mode for themselves. Enterprise/Edu Admins can grant developer access to selected members.

Create the app

  1. Open Settings → Apps → Create or Workspace settings → Apps → Create.
  2. Enter a name such as Display.dev.
  3. Set the MCP endpoint to https://api.display.dev/v1/mcp.
  4. Choose OAuth authentication.
  5. Select Scan Tools. Complete the Display.dev sign-in and authorization flow, then wait for the scan to finish.
  6. Review the discovered write and administrative actions, then select Create.

The app appears as a development app under Settings → Apps → Enabled Apps. Ask ChatGPT to publish a small HTML or Markdown file and confirm that it returns a Display.dev URL.

Only an Admin or Owner can publish the app for the workspace. Enterprise/Edu Admins can also restrict who may use it and disable specific actions.

Reconnect when authorization expires

If ChatGPT returns 401 or stops reaching Display.dev after the original authorization, open Settings → Apps, disconnect the development app, and connect it again. Complete the OAuth flow again before retrying the tool call.

You can revoke Display.dev's side of the connection from Connected apps. Revocation makes the next tool call fail until you reconnect in ChatGPT.

Common errors

  • App creation is unavailable – confirm your ChatGPT plan, workspace role, and developer-mode access.
  • Tool scan fails – confirm the endpoint is exactly https://api.display.dev/v1/mcp, then retry the scan and OAuth flow.
  • No organization appears during authorization – create or join a Display.dev organization first.
  • A publishing action is missing – confirm the workspace allows full MCP write actions and refresh the app's actions.
