Set up in three steps

1
Pick the app
Create a free HeyMyApps account and choose Greenhouse Harvest from the app list.
2
Paste your key
In Greenhouse go to Configure → Dev Center → API Credential Management and create a Harvest v3 (OAuth) credential, ideally tied to an Integration System User. Choose its permissions, then copy the Client ID and Client secret into HeyMyApps. Greenhouse shows the secret only once.
3
Add the link to your AI
You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
1. Click your name, then Settings › Connectors › Add custom connector.
2. Paste your link as the Remote MCP server URL.
3. Switch it on from the + menu in a chat.

Questions

What can the AI do in Greenhouse?

The AI can read jobs, job posts, stages, applications, candidates, attachments, interviews, scorecards, offers, sources, tags, rejection reasons, departments, offices and users. It can create and update candidates, tag them, move applications, reject or unreject them, and mark an application as hired.

Does the AI see my Greenhouse credentials?

No. Your Greenhouse client secret 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, and the permissions on the Harvest credential limit what can be reached. Candidate data is personal data, so you can start read-only and keep reject_application off if a person should make every rejection. Hiring closes the opening, and it 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 HeyMyApps 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?

Greenhouse connects with OAuth, and OAuth connections need the HeyMyApps Pro plan or above. HeyMyApps also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task.

Can the AI send rejection emails to candidates?

Only if you let it. reject_application can include a rejection email template and a send time, and then Greenhouse emails the candidate. Leave the tool off, or require approval for it, if you want to check every rejection first. unreject_application puts an application back in its pipeline.
