FuseDesk for AI agents

FuseDesk is a customer support platform for managing cases, email conversations, chats, and contacts across support teams handling customer questions from multiple channels. 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.

await arc0.policies.set('fusedesk', {
  read: 'allow',

04 · AUTH AND DATA

How FuseDesk connects.

Users add their FuseDesk 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 FuseDesk 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

FuseDesk and Arc0, answered.

Q01

Can I use FuseDesk with Claude, ChatGPT or Cursor?

Yes. Connect FuseDesk 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 FuseDesk actions you allow.

Q02

How do users connect FuseDesk?

Users add their FuseDesk 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 FuseDesk actions can my agent take?

27 in total: 14 read, 11 write and 2 destructive, such as “create Case”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in FuseDesk?

Yes. Actions like “close Chat” 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 FuseDesk too?

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