The ChatGPT app provides the MCP connection. ChatGPT does not support plugins with rules, skills, or agents — but all 12 Maindex MCP tools are available once connected.
Until the app is approved, you can connect manually via Developer Mode:
- Open Settings → Apps & Connectors → Advanced settings
- Toggle Developer Mode on
- Click Create under Apps & Connectors
| Field | Value |

Maindex works with any MCP client via the raw MCP server URL. See the MCP Setup Guide for step-by-step instructions for Windsurf, Gemini CLI, LM Studio, Open WebUI, Msty, and more.
