In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-calendarwhat's on my calendar tomorrow?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-calendar
The caller's Apple iCloud calendar over CalDAV, as an MCP server.
Tool | |
| events in a time window, across the caller's calendars |
| add an event to the write calendar (created on first write) |
| change title/time/place/description of an event by id |
| gated: |
| which client and principal your key acts as |
Accounts are per principal (config/accounts.example.yaml): a user id forwarded by a
trusted client such as Jarvis (X-On-Behalf-Of: owner), or a client's own id. The file names
the environment variables that hold each account's Apple ID and app-specific password — the
credentials themselves stay in the environment and never reach the model. A caller without an
account gets an error, never someone else's calendar.
Part of the Jarvis tool servers; built on jarvis-mcp-kit (API keys, rate limits, logs).
Run
cp .env.example .env # ICLOUD_CALDAV_USER, ICLOUD_APP_PASSWORD
cp config/clients.example.yaml config/clients.yaml
cp config/accounts.example.yaml config/accounts.yaml
uv run --env-file .env mcp-calendar serve # http://localhost:8010/mcp/calendarKubernetes: deploy/kubernetes.yaml. Personal data — keep it ClusterIP-only.
