Use Relay with ChatGPT
Connect Relay on chatgpt.com or in the ChatGPT desktop app, and check the connection.
This connection works on ChatGPT Free and paid plans. On Business, Enterprise, and Edu, workspace settings can limit custom connections.
Connect Relay before you ask ChatGPT for SEO research. ChatGPT cannot add the connection by itself. If you paste the setup prompt into a chat, it gives you these steps.
ChatGPT on the web
-
Sign in to chatgpt.com.
-
If you see it, open Settings → Security and login and turn on Developer mode.
-
Open Plugins, select +, then Create MCP App. In older versions, look for Settings → Apps → Advanced settings → Developer mode, then Create.
-
Enter these details:
Field Value Name RelayServer URL https://relay.playbookmedia.io/mcpAuthentication OAuthType the full address, including
https://. -
Create the connection, sign in to Relay in the window that opens, and approve. If the new app needs installing, open it under Personal and select Install.
-
Start a new chat, open the + menu, and select Relay.
-
Send the connection check below.
You do not need an API key for ChatGPT; sign-in handles it. A custom connection gives ChatGPT Relay's tools. It does not install skill files, but you can still ask for audits or keyword research in plain language.
ChatGPT desktop and Codex
To use Relay in Codex inside the desktop app, start a new Codex chat and paste the setup prompt. Or follow the Codex guide. Codex and ChatGPT on the web use separate connections.
Check the connection
Send this in a new chat with Relay selected:
Use Relay to check my connection and list my projects. Do not run SEO research or create anything.ChatGPT should call Relay and list your projects. An empty list still means it works. These reads are free.
Then try:
Use Relay to help me choose one SEO task for my website. Ask about my goal before starting paid research.Troubleshooting
| What you see | What to do |
|---|---|
| No Developer mode or Create MCP App option | Check Settings → Security and login. On a workspace plan, ask your admin whether custom connections are allowed. |
| "Error fetching OAuth configuration: Unsafe URL" | Enter https://relay.playbookmedia.io/mcp in full, with no spaces. |
| ChatGPT asks for a client ID or secret | Keep OAuth selected and wait for discovery. If asked, choose Dynamic Client Registration. You do not need your own client credentials. |
| The sign-in window never appears | Allow pop-ups for chatgpt.com, then retry authentication from the connection's details. |
| ChatGPT gives general advice instead of using Relay | Select Relay in the + menu and resend the connection check. |
Still stuck? Email team@playbookmedia.io with your plan, web or desktop, the step that failed, and the error. Never include passwords, API keys, or sign-in codes.
Update Relay
For a custom connection, open its details under Plugins, select Refresh to reload the tools, and start a new chat. If sign-in has expired, sign in again.
