Set up in three steps

1
Pick the app
Create a free HeyMyApps account and choose Greenhouse from the app list.
2
Paste your key
Paste the Client ID and Client secret from a Harvest V3 (OAuth) API credential. In Greenhouse open API Credentials, click Create new API credentials, choose Harvest V3 (OAuth), save and configure the scopes the integration may use. List endpoints need the credential's user to be a Site Admin. HeyMyApps uses the credential to get access tokens, so there is no separate sign-in.
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?

It can read candidates, applications, stage history, jobs, openings, job posts, stages, interview types, interviews, scorecards, offers, attachments, tags, users, departments, offices and rejection reasons. It can create and update candidates and jobs, tag candidates, add attachments, move applications, record and change interviews, and reject or hire applications.

Does the AI see my Greenhouse credentials?

No. Your Greenhouse 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 read-only. Rejecting can email the candidate, hiring fills a job opening and deleting an interview cannot be undone, so these 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 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. You also need your own Greenhouse account.

Will the candidate be emailed when the AI rejects them?

Only if the AI includes a rejection email in the request. Without it, the application is rejected in Greenhouse and no email goes out. You can require your approval for rejections, so you see the details before anything happens.
