Greenhouse for AI agents

Greenhouse is applicant tracking software that helps recruiting teams manage candidates, jobs, and the hiring pipeline. People teams rely on it to keep employee records accurate without manual double entry. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

04 · AUTH AND DATA

How Greenhouse connects.

Users sign in to Greenhouse on Arc0 Connect and approve the scopes you request. Build with Arc0’s Greenhouse OAuth app, or bring your own so the Greenhouse consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Greenhouse connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Greenhouse and Arc0, answered.

Q01

Can I use Greenhouse with Claude, ChatGPT or Cursor?

Yes. Connect Greenhouse to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Greenhouse actions you allow.

Q02

How do users connect Greenhouse?

Q03

Which Greenhouse actions can my agent take?

134 in total: 57 read, 56 write and 21 destructive, such as “create Greenhouse job”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Greenhouse?

Yes. Actions like “delete Greenhouse job note” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Greenhouse too?

Yes. The same Greenhouse connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
