HackerRank Work for AI agents

HackerRank Work provides coding interviews and technical assessments, helping hiring teams evaluate engineering candidates through real-time collaboration and data-driven scoring during the recruiting process. 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 HackerRank Work connects.

Users add their HackerRank Work api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

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

AUTH: API key
CREDENTIALS: Per-tenant encrypted vault
MODEL SEES: Results only, never credentials
AUDIT LOG: Every call, on every plan

HackerRank Work and Arc0, answered.

Q01

Can I use HackerRank Work with Claude, ChatGPT or Cursor?

Yes. Connect HackerRank Work 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 HackerRank Work actions you allow.

Q02

How do users connect HackerRank Work?

Users add their HackerRank Work api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which HackerRank Work actions can my agent take?

3 in total: 0 read, 3 write and 0 destructive, such as “list Companies”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in HackerRank Work?

Yes. Allow read actions and deny writes in the HackerRank Work policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call HackerRank Work too?

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