Connect Claude & ChatGPT to CustomGPT.ai

Ask your AI to put a question to one of your CustomGPT.ai agents, go through past conversations or show the source behind a citation. It can create and update agents, check which documents an agent has indexed and re-index one, list the leads captured in chats and read agent stats and your plan limits.

Questions

What can the AI do in CustomGPT.ai?

It can list and read your agents, their settings, sources, documents and stats, and read conversations, messages, citations and captured leads. It can start conversations and send questions to an agent, rate answers, create and update agents, re-index a document and delete a conversation. It can also read your user profile and plan limits.

Does the AI see my CustomGPT.ai API key?

No. You paste your CustomGPT.ai API key into PipMCP once. It is encrypted at rest, never shown to the AI and never shown again after you save it. The AI only gets the results of the tools you have switched on.

Can I control what the AI is allowed to do?

Yes. Switch on only the tools you want, for example asking agents and reading conversations without creating or changing agents. Actions that cannot be undone, like delete_conversation, can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan, and you do not need a credit card to start. Paid plans are billed per completed task. You also need your own CustomGPT.ai account.

Can my AI assistant ask questions to my CustomGPT.ai agent?

Yes. The AI starts a conversation with the agent, sends your question and gets the agent's answer back, with citations to the sources it used. You can then ask it to open a citation to see the source, or to continue in the same conversation.
