From 79616c9da4d90269e2be77a0ceb1354a97ffa194 Mon Sep 17 00:00:00 2001 From: krypticmouse Date: Thu, 26 Mar 2026 01:37:28 +0000 Subject: [PATCH] feat: add Google Calendar connector with event sync Implements GCalendarConnector (registered as "gcalendar") following the gmail.py pattern: module-level API functions for calendarList and events.list, _format_event helper for human-readable content, paginated sync across all calendars, and three MCP tools (get_events_today, search_events, next_meeting). Includes 6 tests covering not_connected, auth_url scope, sync document fields, disconnect, mcp_tools, and registry.
