Same site, any assistant
ChatGPT
Add the connection in settings, then ask in the chat you already use.
Grok
New connector, choose Custom, paste the same URL.
Codex
Point it at the same URL from a config file and work from your editor.
Gemini, Perplexity, Le Chat
Any assistant that speaks MCP connects the same way.
One connection
Your website doesn’t care which assistant is asking.
Not everyone works in the same assistant. ChatGPT, Grok and Gemini connect in settings. Codex and other CLI tools read a config file. The site behaves the same either way.
