How do I create a Calendly Personal Access Token?

Log in to the [**Calendly Dashboard**](https://calendly.com), go to **Integrations & Settings > API & Webhooks**, and generate a Personal Access Token. Copy the token immediately — it won't be shown again.

Can I see who booked a meeting?

Yes! Use `list_invitees` to see all attendees across your events, or `list_scheduled_events` to see upcoming meetings with their invitee URIs. Then use `get_invitee` with the invitee UUID to get their full name, email, timezone and answers to custom questions.

Can I check availability before booking?

Yes! Use `get_user_availability` with the user's URI, start time and end time (ISO 8601 UTC). It returns the user's scheduling rules, busy times and date overrides so you can identify open slots before creating a booking.

Can I set up webhooks for new bookings?

Yes! Use `create_webhook` with your callback URL, events like 'invitee.created' and 'invitee.canceled', and the scope (your user or organization URI). Optionally provide a signing key for verification. You can audit existing webhooks with `list_webhooks`.

Calendly Alternative + Pydantic AI FAQ

Common questions about integrating Calendly Alternative MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
