ChatGPT

#Connect

1. Settings → Connectors → Create (developer mode must be enabled).

2. Paste the endpoint:

   https://marketing-api.keyescode.com/mcp

3. Choose OAuth as the authentication method and complete the flow in the browser. The consent screen is where you narrow the connection to one organization, optionally one business, and to read-only or read-and-propose.

ChatGPT discovers everything else it needs from the endpoint's own metadata — /.well-known/oauth-protected-resource, /.well-known/oauth-authorization-server and dynamic client registration at POST /oauth/register. There is nothing to register by hand.

#First prompts

• "Using Marketing OS, which ad sets spent more than £100 last week and returned less than break-even?"
• "Check my AI search visibility and tell me which competitors are named instead of me."

#If something goes wrong

Only read tools appear — the grant is read-only. Reconnect and pick "Read and propose changes". The rest is in troubleshooting.
