Add gcal tool

--- name: add-gcal-tool description: Add Google Calendar as an MCP tool (list calendars, list/search/create events, free/busy queries) using OneCLI-managed OAuth. Supports multiple calendars and multiple accounts. Mirrors/add-gmail-tool’s stub pattern:no raw credentials ever reach the container; OneCLI injects real tokens at request time. --- # Add Google Calendar Tool (OneCLI-native) This skill wires [@cocal/google-calendar-mcp](https://github.com/cocal-com/google-calendar-mcp) into selected agent groups. The MCP server reads stub credentials containing the onecli-managed placeholder; the OneCLI gateway intercepts outbound calls to calendar.googleapis.com / oauth2.googleapis.com and replaces the bearer with the real OAuth token from its vault. Why this package (and not gongrzhe's): @gongrzhe/server-calendar-autoauth-mcp only supports the primary calendar and exposes 5 tools (no list_calendars). @cocal/google-calendar-mcp explicitly supports multiple calendars and multiple accounts, and is actively maintained. Exposed tools (accessible at mcp__calendar__<name>; the exact set depends on the version:run tools/list against the MCP server to list them): list-calendars, list-events, search-events, create-event, update-event, delete-event, get-event, list-colors, get-freebusy, get-current-time, plus multi-account management tools. Why this pattern: v2’s invariant is that containers never receive raw API keys (CHANGELOG 2.0.0). The same stub pattern/add-gmail-tools uses. This skill is deliberately a standalone component, not a combined “Google Workspace” skill : it installs independently and uninstalls cleanly. ## Phase 1: Pre-flight ### Verify that OneCLI has Google Calendar connected ``bash onecli apps get --provider google-calendar ` Expected: "connection": { "status": "connected" } with scopes including calendar.readonly and calendar.events . If not connected, tell the user: > Open the OneCLI web UI at http://127.0.0.1:10254, go to Apps → Google Calendar, and click Connect. Sign in with the Google account the agent should act as. calendar.readonly + calendar.events are the minimum useful scopes. ### Verify stub credentials exist The stub lives at ~/.calendar-mcp / by convention (shared with /add-gmail-tool's sibling). cocal doesn't default to this path (it uses ~/.config/google-calendar-mcp/tokens.json) : we override via env vars below so it reads our stubs instead. `bash ls -la ~/.calendar-mcp/gcp-oauth.keys.json ~/.calendar-mcp/credentials.json 2>&1 ` If both exist with onecli-managed : `bash grep -l onecli-managed ~/.calendar-mcp/gcp-oauth.keys.json ~/.calendar-mcp/credentials.json ` ...skip to Phase 2. If either file has real credentials (no onecli-managed ), **STOP** : back up and delete before proceeding. If absent, write them: `bash mkdir -p ~/.calendar-mcp cat > ~/.calendar-mcp/gcp-oauth.keys.json <<'EOF' { "installed": { "client_id": "onecli-managed.apps.googleusercontent.com", "client_secret": "onecli-managed", "redirect_uris": ["http://localhost:3000/oauth2callback"] } } EOF cat > ~/.calendar-mcp/credentials.json <<'EOF' { "access_token": "onecli-managed", "refresh_token": "onecli-managed", "token_type": "Bearer", "expiry_date": 99999999999999, "scope": "https://www.googleapis.com/auth/calendar.readonly https://www.googleapis.com/auth/calendar.events" } EOF chmod 600 ~/.calendar-mcp/*.json ` ### Verify mount allowlist covers the path `bash cat ~/.config/nanoclaw/mount-allowlist.json ` ~/.calendar-mcp must sit under an allowedRoots entry. ### Check agent secret-mode For each target agent group, confirm OneCLI will inject the Google Calendar token: `bash onecli agents list ` secretMode: all is sufficient. If selective , explicitly assign the Calendar secret. ## Phase 2: Apply Code Changes ### Check if already applied `bash grep -q 'CALENDAR_MCP_VERSION' container/Dockerfile && \ echo "ALREADY APPLIED : skip to Phase 3" ` ### Add MCP server to Dockerfile Edit container/Dockerfile . Find the pinned-version ARG block and add: `dockerfile ARG CALENDAR_MCP_VERSION=2.6.1 ` If /add-gmail-tool` has already been ap
