Connect from ChatGPT#

Connect ChatGPT to the ZenCreator MCP server by adding one URL and logging in once with your browser. There are no API keys to paste, nothing to install, and no local process to run. ChatGPT handles the OAuth token and its refresh automatically.

The ZenCreator MCP server is a hosted, remote server secured with OAuth 2.1. The only thing you add to ChatGPT is the endpoint URL below.

Prerequisites#

  • A ZenCreator account at https://app.zencreator.pro. You log in with it during the OAuth step.
  • A ChatGPT plan and account that supports custom MCP connectors. Availability depends on your plan, and you may need to enable developer / connector access for your account first.

The endpoint#

Add this URL as a custom MCP connector:

https://mcp.zncr.pro/mcp

Add the connector#

Note: ChatGPT's settings UI changes over time, and the exact menu labels and layout differ between plans, platforms, and releases. The steps below describe what to look for rather than an exact click path. If a label here does not match what you see, look for the equivalent Connectors / custom connector option.

  1. Open ChatGPT Settings.

  2. Look for Connectors (this is where custom MCP connectors live). If you do not see it, you may need to enable developer / connector access for your account first; this option also depends on your plan.

  3. Choose to add a custom connector (sometimes shown as adding a connector by URL).

  4. Paste the server URL:

    https://mcp.zncr.pro/mcp

  5. Save / add the connector.

Log in (OAuth)#

The first time ChatGPT uses the connector, it runs the OAuth login in your browser:

  1. ChatGPT discovers the server's protected-resource metadata and opens your browser.
  2. Log in at ZenCreator.
  3. Approve the consent screen. It grants the scopes mcp.read and mcp.generate.
  4. ChatGPT stores the resulting token and refreshes it automatically. You do not paste anything back.

No API keys are involved at any point. The server is an OAuth 2.1 Resource Server conforming to the MCP 2025-06-18 revision with audience-bound tokens.

Verify it works#

Once the connector is added and you have logged in, ask ChatGPT to call a read-only tool, for example:

Use ZenCreator to show my account and credit balance.

This calls zencreator_get_me and returns your profile, credit balance, and flags such as nsfw_allowed, is_trusted, and out_of_credits. If that succeeds, the connection is working.

You can also ask:

List the ZenCreator generation tools and their prices.

This calls zencreator_list_tools.

Troubleshooting#

  • No Connectors option in Settings. Custom MCP connectors depend on your plan, and you may need to enable developer / connector access. Check that your account and plan support custom connectors.
  • Login window never finishes or tools fail with an auth error. Re-run the connection so the browser OAuth login can complete, then approve the consent screen granting mcp.read and mcp.generate.
  • Generation fails with an out-of-credits signal. Top up at https://app.zencreator.pro/billing. The same out_of_credits flag is also visible via zencreator_get_me.
