Raindrop.io for AI agents

Raindrop.io is a bookmark manager for organizing, tagging, and sharing saved web content. Individuals and teams use it to keep research and reference links organized in collections. 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.

Raindrop.io and Arc0, answered.

Q01

Can I use Raindrop.io with Claude, ChatGPT or Cursor?

Yes. Connect Raindrop.io 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 Raindrop.io actions you allow.

Q02

How do users connect Raindrop.io?

Users add their Raindrop.io 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 Raindrop.io actions can my agent take?

11 in total: 4 read, 5 write and 2 destructive, such as “create Bookmark”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Raindrop.io?

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.

Can my own backend call Raindrop.io too?

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