Can AI agents automate Calendly?

Calendly is automatable today through REST API v2. Agents authenticate with a scoped personal access token as Authorization: Bearer, or with an OAuth app (PKCE, S256) against https://auth.calendly.com. Documented scopes cover availability, event types, scheduled events, routing forms, organizations, webhooks, contacts, and meeting recaps. Booking via POST /invitees requires a paid Calendly plan. Routing-form reads require Teams or higher. Webhook subscriptions are user-scoped or organization-scoped: owners and admins may subscribe at either scope; other members are limited to user scope; routing_form_submission.created accepts only organization scope. MCP list tools such as event_types-list_event_types map the same user-or-org API v2 calls. A first-party hosted MCP at https://mcp.calendly.com requires OAuth 2.1 Authorization Code plus PKCE with Dynamic Client Registration at calendly.com/oauth/*; personal access tokens, console-issued client secrets, and the API OAuth host auth.calendly.com are not MCP auth today. Self-hosting is not supported. Calendly's pricing page names Zapier and Microsoft Power Automate among automations. This record excludes Chili Piper, Google Calendar, and Microsoft Outlook. Computer-use viability is unassessed. API and MCP both score 8. API is the best path because a personal access token works without a DCR-capable client.
