ChatGPT

Add Display.dev as a custom connector in ChatGPT with auto-discovered OAuth.

On this page

ChatGPT supports MCP custom connectors with OAuth. Pasting Display.dev's MCP URL into the connector-setup form auto-discovers everything ChatGPT needs to register and sign you in — no config file, no API key, no developer console. Sign in with your work email and approve.

Add as a custom connector

  1. In ChatGPT, open Settings → Connectors → Create / Add a custom connector.
  2. Paste /v1/mcp into the MCP Server URL field.
  3. Select OAuth as the authentication method. ChatGPT fetches Display.dev's authorization-server and protected-resource metadata and auto-fills the authorization endpoint, token endpoint, scope (mcp:tools), and registration endpoint — leave those fields as detected.
  4. Save the connector. ChatGPT opens a browser tab on Display.dev.
  5. Sign in with your work email. Display.dev sends a 6-digit OTP; paste it back into the browser tab.
  6. Pick the organization to authorize (if you belong to more than one), review the consent screen, and click Authorize.

The browser tab closes itself. Back in ChatGPT, Display.dev's tools (publish, share, rename, find, get, export, delete) appear under the connector and are callable from any conversation that enables it.

To revoke the connection later, open app.display.dev/settings/connectors and click Revoke. ChatGPT's next tool call returns an auth error; re-authorize from the same connector panel in ChatGPT.

Common errors

  • "Connection failed" or "Invalid URL" — make sure the URL is exactly /v1/mcp. Trailing slash matters.
  • OTP email doesn't arrive — check spam, and confirm the email matches the one your organization signed up with.
  • Authorize screen says "no organization" — your account isn't a member of any active organization. Create or join one first.
  • Tool calls 401 — the connector grant was revoked from app.display.dev/settings/connectors, or ChatGPT lost its stored credentials. Re-authorize from ChatGPT's connector panel.
  • Custom connectors not available in your account — connector creation is limited by ChatGPT plan; check your plan's connector capabilities or contact your ChatGPT admin.
