Where things stand
In developer mode ChatGPT can connect custom MCP servers (Pro, Plus, Business, Enterprise, Education). According to OpenAI, though, it only knows OAuth or no authentication — it cannot send a fixed API key in a header, which is what Indizio requires.
So there is no guide here that would work today. We will write one as soon as either side changes that.
What works instead
- Claude — as a connector in claude.ai or in Claude Code.
- Your own automation — via n8n or a Python script, then use the results in ChatGPT.
