Google Calendar for AI agents

Google Calendar manages schedules, events, and reminders, and integrates with Gmail and other Workspace apps. Teams use it to manage this booking flow without a manual back-and-forth over email. 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.

  2. 02You set the rulesReads run, writes like “create Event” can wait for the user, and “delete event” can be denied outright.
  3. 03Any agent can actYour agent calls Google Calendar through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('google_calendar', {
  read: 'allow',
  write: 'ask',        // create_event
  destructive: 'deny',  // delete_event
})

04 · AUTH AND DATA

How Google Calendar connects.

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

The same Google Calendar 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

Google Calendar and Arc0, answered.

Q01

Can I use Google Calendar with Claude, ChatGPT or Cursor?

Yes. Connect Google Calendar 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 Google Calendar actions you allow.

Q02

How do users connect Google Calendar?

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

Q03

Which Google Calendar actions can my agent take?

50 in total: 10 read, 34 write and 6 destructive, such as “create Event”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Google Calendar?

Yes. Actions like “delete event” 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 Google Calendar too?

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