You.com for AI agents
You.com is a search and research assistant, used by teams that want a cited, synthesized answer to a question rather than a list of links to click through. 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.

How You.com connects.
Users add their You.com 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 You.com connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

You.com and Arc0, answered.
Can I use You.com with Claude, ChatGPT or Cursor?
Yes. Connect You.com 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 You.com actions you allow.
How do users connect You.com?
Users add their You.com 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.
Which You.com actions can my agent take?
8 in total: 5 read, 3 write and 0 destructive, such as “create You.com Research”. Your policies decide which of them each agent may call.
Can I make my agent read-only in You.com?
Yes. Allow read actions and deny writes in the You.com policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call You.com too?
Yes. The same You.com connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug You.com into your agent.
Your users connect You.com once, under your brand. Your agent gets 8 actions behind your policies, with every call on the record.
