Klazify for AI agents

Klazify is a content classification API that categorizes websites, extracts logos and social links, and identifies a site's technology stack. 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 Klazify connects.

Users add their Klazify 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 Klazify 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

Klazify and Arc0, answered.

Q01

Can I use Klazify with Claude, ChatGPT or Cursor?

Yes. Connect Klazify 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 Klazify actions you allow.

Q02

How do users connect Klazify?

Users add their Klazify 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 Klazify actions can my agent take?

8 in total: 6 read, 2 write and 0 destructive, such as “categorize URL”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Klazify?

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

Q05

Can my own backend call Klazify too?

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