ChatGPT is OpenAI’s AI assistant. It can connect to remote MCP servers through custom plugins. 💬

MCP features supported: Tools, Dynamic Client Registration

​
Setup

1

🧩 Open the Plugins section

In ChatGPT, open Settings and go to Plugins. Click Add in the top right corner and choose Add custom MCP server.

2

📝 Fill in the server details

Enter the following:

  • Name: Wonderflow
  • Description (optional): Query your Wonderflow catalog: topics, feedback analytics, prices, votes, products, and reviews.
  • Connection: select Server URL and enter https://catalog-mcp.wonderflow.ai/mcp
  • Authentication: OAuth

You can also upload an Icon (optional, PNG only, at least 256 x 256 px, maximum 10 KB).

3

🔍 Check the advanced OAuth settings

Open Advanced OAuth settings. The default values detected by ChatGPT are the right ones, so you do not need to change anything. Just verify that:

  • Registration method is set to Dynamic client registration (DCR). A message saying that CIMD is not available is expected, and you can ignore it.
  • Resource is https://catalog-mcp.wonderflow.ai/mcp.
  • OIDC enabled is checked, and the OIDC configuration URL, the userinfo endpoint, and the supported scopes (such as openid, profile, and offline_access) are filled in automatically.

If you changed any of these values by mistake, close the dialog and start again from step 1 to restore the defaults.

4

✅ Create the plugin

Read the notice about custom MCP servers, then click Create as plugin.

5

🔑 Authenticate

A browser window opens for Auth0 login. Log in with your Wonderboard credentials. After authentication you land back in ChatGPT, and the Wonderflow plugin is connected. ✅

You can find it under Plugins → Personal → Created by you.

6

🧪 Test it works

Open a new chat, make sure the Wonderflow plugin is enabled, and ask: “What topics has my catalog discovered recently?”

ChatGPT should call the Wonderflow tools and return results from your catalog. 🎉

ChatGPT works on the catalog you are currently using in the Wonderboard. To change catalog, see Catalogs and scopes.
