Questions

What can the AI do in Hume AI?

It can list and read EVI configs, prompts, custom tools, voices, chats and chat groups, including full transcripts and chat audio. It can create configs and prompts, save new versions of them, save a voice from a text-to-speech generation and delete prompts.

Does the AI see my Hume AI credentials?

No. Your Hume AI API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Deleting a prompt is permanent and can require your approval before it runs, like new versions of configs and prompts. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then 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 with no credit card required. Paid plans bill per completed task. You also need your own Hume AI account. PipMCP is not affiliated with Hume AI.

Does changing a config or prompt overwrite the old one?

No. Updating a config or prompt saves a new version, and the earlier versions stay listed on it. Deleting a prompt is different: it permanently removes the prompt and all its versions.
