Connect Claude & ChatGPT to CATS

Ask your AI to find candidates with a certain skill in CATS, add someone to a job's pipeline, or show who is at the interview stage. It can create and update candidates, jobs, companies and contacts, move candidates through pipeline statuses, log calls and meetings and manage to-do tasks. Recruiting admin gets done while you talk about the role.

Questions

What can the AI do in CATS?

The AI can search, read, create and update candidates, jobs, client companies and contacts. It can add candidates to a job's pipeline, move them between pipeline statuses, change job status, list and log activities on candidates, and list, create and update to-do tasks. It can also list users, job statuses and pipeline statuses.

Does the AI see my CATS API key?

No. Your CATS credentials are encrypted at rest and never shown to the AI. After you save them, they are 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 read-only tools. Moving a candidate to a new pipeline status can fire your account's automated triggers, so that action can require your approval before it runs. 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 CATS account.

Does my old CATS API key work?

No. PipMCP uses the CATS v3 API, which needs a v3 API key. Transaction codes from the old API do not work. You create a v3 key on the Administration settings page in CATS.
