How to Use the Notion Calendar (formerly Cron) MCP in Claude

Q: Can I view team schedules in Notion Calendar (formerly Cron) using Claude Desktop?

Yes, if you have shared access, the agent uses listcalendars to fetch all available calendars in your account. From there, it can run getfreebusy to see when your coworkers are booked.

Q: What happens if I have a conflict on my Notion Calendar (formerly Cron) when using Claude Desktop?

The agent runs getavailability to scan your existing slots before making any changes. If it detects a conflict, it will alert you in the chat rather than blindly running createevent over an existing block.

Q: Can I update existing calendar invites?

Yes, the agent uses updateevent to modify times, titles, or attendees on your active schedule. It targets the specific event ID grabbed from getevent to make the precise change you asked for.

Perplexity

Check availability and insert meetings via Claude Desktop

The `get_availability` tool queries your Notion Calendar to find open slots without you leaving the desktop app. It pulls your real-time calendar state directly into Claude's local context window so your agent knows exactly when you can talk. Once you find a slot, Claude Desktop uses `create_event` to write the meeting straight to your calendar. This local MCP server connection runs as a background process on your machine, so your calendar updates happen instantly without hitting external middleware.

Clean up messy schedules using this MCP Server

The `delete_event` tool lets Claude Desktop instantly wipe canceled meetings or overlapping conflicts from your Notion Calendar. You just tell the desktop client which block to clear, and it targets the exact event ID to clean up your day. To make sure you don't delete the wrong thing, the agent uses `list_events` first to check the title and time. This keeps your local daily layout accurate without requiring you to open a browser tab to manually check the change.

Share booking options with one quick chat command

The `get_scheduling_links` tool pulls your active scheduling links directly into your Claude Desktop chat window. Instead of hunting through your settings, you ask the agent to grab the right link for a specific meeting type. Combining this with `get_free_busy` lets Claude Desktop check your active graph overlaps before sending a link. This means you never send a booking link for a day that is already packed with internal commitments.
