Can my agent create events on my synced Google or Outlook calendars?

Yes. When you use the 'create_event' tool, the agent commands the Notion Calendar backend to generate the meeting overlay, which is then synchronized directly to your connected upstream provider logic.

How do I check if my team members are free for a meeting on a specific date?

Use the 'get_free_busy' tool. Provide a JSON array of email addresses and the target date. Your agent will analyze the cross-references and identify available hourly slots, predicting any potential collision limits.

Can I retrieve my scheduling links via chat to share with clients?

Absolutely. The 'get_scheduling_links' tool extracts the precise active booking forms tied directly to your Notion Calendar profile, allowing your agent to provide you with ready-to-share links instantly.

Notion Calendar (formerly Cron) + Claude Desktop FAQ

Common questions about integrating Notion Calendar (formerly Cron) 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.
