Connect Claude & ChatGPT to Hatz AI

Use the apps and workflows you have built in Hatz AI straight from Claude, ChatGPT or Cursor. Your AI can find an app, read which inputs it expects and run it, or start a workflow and check on the job until the output is ready. It can also send a conversation to a Hatz model, list your agents and look up the files in your workspace.

“Which Hatz apps and workflows can I use?”
The AI lists the apps and workflows in your workspace with their IDs.
“Run our 'Proposal writer' app for Nordic Foods ApS.”
It reads the app's input fields, fills them in from your request and returns the app's answer.
“Start the monthly report workflow and tell me when it is done.”
It starts the workflow, gets a job ID back and checks the job status and results.

Questions

What can the AI do in Hatz AI?

It can list and read your apps and workflows, run an app with its inputs, start a workflow and check the job's status and results, and get a download link for a workflow's output file. It can also list chat models, agents and workspace files, and send a conversation to a Hatz model.

Does the AI see my Hatz AI API key?

No. Your Hatz 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 with lookups only. Running apps and starting workflows can require your approval before they run. 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 Hatz AI account.

I lost my Hatz AI API key. What now?

Hatz AI shows a new API key only once, when you generate it. If you did not copy it, go to Workspace > API Keys in Hatz AI, generate a new key and paste it into PipMCP.
