Codex app

Codex in the ChatGPT desktop app shares its MCP configuration with the Codex CLI on the same computer: a server added there is already here. To add it in the app:

Setup

Open Settings → MCP servers and select Add server.
2
Name it pumati, choose Streamable HTTP and enter this URL. Save, then select Restart.
```
https://mcp.pumati.app/mcp
```
Select Authenticate next to pumati and sign in at pumati.app.

A Pumati plugin you added in ChatGPT also works in Codex in the desktop app.
