Connect Claude Code

For Claude Code (the terminal tool) a single command is enough. The exact address is shown in the app under AI assistant → “Connect the assistant” → Claude Code.

For a new assistant connection, only each account’s provider-designated primary calendar is preselected, within your plan limit. You can select additional calendars. If the provider does not identify a primary calendar, you choose it yourself. Selected calendars start with the maximum supported permissions; the sliders icon next to the access label opens the detail level, write and management permissions for that calendar. Use Share to confirm your selection. If a plan offer appears, you can skip it directly. Access is then granted; the success screen shows example prompts and an app link. It returns you to the assistant after eight seconds, or immediately via the return button. Reconnecting preserves existing permissions where they remain available.

Step by step

1. Run this command in your project:

   claude mcp add --transport http kalender-sync https://app.kalender-sync.de/mcp

2. Start Claude Code and type /mcp. Pick kalender-sync, then Authenticate — that opens our sign-in in the browser.
3. Sign in and confirm the grant on the consent screen — pick the calendars, set the detail level per calendar. Only now does the access exist.

Then you can dive right in, e.g.: “Which calendars are shared via Kalender Sync?”, “Where do I have two hours in one block this week?” or “When is my dentist appointment?”

Disconnect again

claude mcp remove kalender-sync removes the server only locally in Claude Code. The authoritative revoke is the one in Kalender Sync under AI assistant → Revoke → Revoke access.
