Linkhut for AI agents

LinkHut is a minimalist bookmarking tool teams use to organize and share saved links with tags in one shared place. 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 Linkhut connects.

Users sign in to Linkhut on Arc0 Connect and approve the scopes you request. Build with Arc0’s Linkhut OAuth app, or bring your own so the Linkhut consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Linkhut 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

Linkhut and Arc0, answered.

Q01

Can I use Linkhut with Claude, ChatGPT or Cursor?

Yes. Connect Linkhut 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 Linkhut actions you allow.

Q02

How do users connect Linkhut?

Users sign in to Linkhut on Arc0 Connect and approve the scopes you request. Build with Arc0’s Linkhut OAuth app, or bring your own so the Linkhut consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

Q03

Which Linkhut actions can my agent take?

5 in total: 2 read, 2 write and 1 destructive, such as “update Bookmark”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Linkhut?

Yes. Actions like “delete bookmark” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Linkhut too?

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