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.
