| description | Create, update, delete, and query Google Calendar events using gcallm CLI, MCP tools, or direct API calls. |
Three access methods, in order of preference:
Best for creating events from natural language or file input.
# Direct text
gcallm "Meeting with Sarah tomorrow at 3pm"
# From file (preferred for multi-event)
cat /tmp/gcal/events.txt | gcallm
# From clipboard
gcallm
# From screenshot
gcallm -s "Add events from this screenshot"
# Ask questions
gcallm ask "What's on my calendar today?"
gcallm ask "Am I free Thursday afternoon?"
When the google-calendar MCP server is connected, these tools are available:
mcp__google-calendar__list-events # List events in a time range
mcp__google-calendar__search-events # Search by query string
mcp__google-calendar__create-event # Create event
mcp__google-calendar__update-event # Update event (supports recurring with modificationScope)
mcp__google-calendar__delete-event # Delete event
Use modificationScope to control which instances are affected:
all — update/delete the entire seriesthis — only this instancethisAndFollowing — this and all future instances| ID | Color |
|---|---|
| 1 | Lavender |
| 2 | Sage |
| 3 | Grape |
| 4 | Flamingo |
| 5 | Banana |
| 6 | Tangerine |
| 7 | Peacock |
| 8 | Graphite |
| 9 | Blueberry |
| 10 | Basil |
| 11 | Tomato (Red) |
When MCP tools are unavailable, use the REST API with stored OAuth tokens.
