Calendly for AI agents

Calendly automates appointment scheduling with shareable booking links, calendar availability checks, and reminders, cutting out the email back-and-forth over meeting times. 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.

What agents do in Calendly.

01

Check open time slots

Check an event type's open time slots before sharing a scheduling link with someone.

02

Create a single-use link

Create a single-use scheduling link for a one-off meeting that shouldn't be reused.

03

Confirm before canceling an event

02 · ACTIONS

57 Calendly actions, graded by risk.

Every Calendly action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

04 · AUTH AND DATA

How Calendly connects.

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

The same Calendly 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

Calendly and Arc0, answered.

Q01

Can I use Calendly with Claude, ChatGPT or Cursor?

Yes. Connect Calendly 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 Calendly actions you allow.

Q02

How do users connect Calendly?

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

Q03

Which Calendly actions can my agent take?

57 in total: 36 read, 13 write and 8 destructive, such as “create share”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Calendly?

Yes. Actions like “delete invitee data” 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 Calendly too?

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