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 + Claude Desktop FAQ

Common questions about integrating Calendly Alternative MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
