Hacker News for AI agents

Hacker News is Y Combinator's tech news aggregator, featuring user-submitted stories and discussion on startups and programming. People use it to stay current on a topic without checking multiple sources by hand. 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 Hacker News connects.

Hacker News needs no credentials. Arc0 still applies your policies and records every call, so public tools get the same controls as private ones.

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

Hacker News and Arc0, answered.

Q01

Can I use Hacker News with Claude, ChatGPT or Cursor?

Yes. Connect Hacker News 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 Hacker News actions you allow.

Q02

How do users connect Hacker News?

Hacker News needs no credentials. Arc0 still applies your policies and records every call, so public tools get the same controls as private ones.

Q03

Which Hacker News actions can my agent take?

14 in total: 14 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Hacker News?

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

Q05

Can my own backend call Hacker News too?

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