Zoho Mail for AI agents

Zoho Mail is business email hosting with calendar and admin controls, used by companies that want an ad-free, managed email service. 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 Zoho Mail connects.

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

The same Zoho Mail 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

Zoho Mail and Arc0, answered.

Q01

Can I use Zoho Mail with Claude, ChatGPT or Cursor?

Yes. Connect Zoho Mail 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 Zoho Mail actions you allow.

Q02

How do users connect Zoho Mail?

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

Q03

Which Zoho Mail actions can my agent take?

29 in total: 2 read, 24 write and 3 destructive, such as “update Group Settings”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Zoho Mail?

Yes. Actions like “delete Email” 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 Zoho Mail too?

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