Can the AI agent cancel an upcoming meeting on my behalf?

Yes. Provide the booking ID (which you can ask the agent to find) and the cancellation reason. The agent triggers the exact routine in Appointlet to withdraw the booking and safely releases the block on your calendar while notifying the invitee.

I need attendee form answers before a call. Can the agent get them?

Absolutely. Using the `get_booking` and `list_bookings` capabilities, your AI agent surfaces the raw intake form fields filled out by attendees when booking their time. It's an instant method to read out context without switching screens.

Can I edit the schedule of round-robin assignees using the agent?

No. The MCP server is optimized as an observability, lookup, and action-oriented companion. It reads the organizational hierarchy, list members, and checks statuses, but modifying overarching structural logic requires entering the Appointlet dashboard.

Appointlet + Claude Desktop FAQ

Common questions about integrating Appointlet 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.
