# Book a meeting

Books an invitee into an open time on an event type and returns the invitee with links to cancel or reschedule.

Note: Needs a paid plan (Standard or above); the Free plan gets a 403. Take `start_time` in UTC from the event type's available times. Calendly sends the calendar invite and notifications as if the invitee had booked on the page.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "calendly": { "url": "https://mcp.calendly.com" } } }
```

Call the MCP tool `meetings-create_invitee`.

Server URL: https://mcp.calendly.com

### API (official)

- Base URL: https://api.calendly.com
- Endpoint: `POST /invitees`
- Auth: send the header `Authorization: Bearer $CALENDLY_API_KEY`
- Get a key: https://calendly.com/integrations/api_webhooks
- Docs: https://developer.calendly.com/api-docs/overview/api/reference

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
