#+TITLE: Calendar Reference
#+AUTHOR: Craig Jennings & Claude
Tool recipes, authentication, and credentials for Craig's calendar
setup. Three access methods, in order of preference.
* Google Calendar MCP Server (preferred for all calendar operations)
Craig has the =@cocal/google-calendar-mcp= MCP server configured at user scope (=~/.claude.json=). It provides full read/write access to Google Calendar via MCP tools.
Two accounts are authenticated:
- *personal* — craigmartinjennings@gmail.com (primary: "Craig Google")
- *work* — craig.jennings@deepsat.com (primary: "Craig Deepsat")
MCP tools available:
- =list-events=, =search-events=, =get-event= — read events
- =create-event=, =create-events= — add events
- =update-event= — modify events
- =delete-event= — remove events
- =list-calendars=, =list-colors= — calendar metadata
- =get-freebusy= — check availability
- =manage-accounts= — add/remove/list authenticated accounts
- =respond-to-event= — accept/decline invitations
- =get-current-time= — current time in any timezone
Use =account_id: "personal"= or =account_id: "work"= to specify which account.
Default calendar for adding events: "Craig Google" (personal account).
Calendar workflows are available alongside this reference: add-calendar-event, edit-calendar-event, delete-calendar-event, read-calendar-events.
If re-authentication is needed:
- Use the =manage-accounts= MCP tool with =action: "add"= and the account nickname
- OAuth credentials: =~/projects/homelab/assets/gcp-oauth.keys.json=
- Google Cloud app is in production mode (tokens don't expire after 7 days)
- See =~/projects/homelab/.ai/gcalcli-setup.org= for Google Cloud project details
* gcalcli (fallback for personal account only)
Craig has =gcalcli= installed via pipx, authenticated to his personal Google account only.
#+begin_src bash
gcalcli agenda # upcoming events
gcalcli calw # weekly view
gcalcli add --title "..." --when "..." --duration "60" # add event
gcalcli search "..." # search events
gcalcli delete "..." # delete event
#+end_src
Use =--calendar "Craig Google"= when adding events.
gcalcli does NOT have access to the work (DeepSat) calendar. Use the MCP server for work calendar operations.
If gcalcli needs re-authentication, credentials are stored in the homelab project: =~/projects/homelab/assets/gcalcli-client-secret.json.gpg= (GPG encrypted).
* Emacs org files (read-only, for viewing schedules)
Craig's calendars are at: =~/.emacs.d/data/*cal.org= (gcal.org, dcal.org, pcal.org)
These files are **READ-ONLY** — NEVER add anything to them.
Use this to:
- Check meeting times and schedules
- Verify when events occurred
- See what's upcoming
- Note: only updated periodically when Emacs is running — may be stale
