MCP server for Skylight Calendar — 102 tools across calendar events (read+write), shared lists (read+write), chores and rewards (read+write), task-box items (read+write), meals (read+write), AI auto-creation (meal-plan + activity-idea generators with draft review/approve), messages and albums (read+write), and frame/device/account settings + calendar + member management (read+write).

Every API request carries the skylight-api-version: 2026-05-01 header (matching the official mobile app); without it some features 422 with "API version does not support …".

Auth

The server uses a headless email+password OAuth2 authorization-code flow — no SSO, no 2FA, no browser extension required. Credentials are always SKYLIGHT_EMAIL + SKYLIGHT_PASSWORD.

On first tool call, the server performs four steps against https://app.ourskylight.com:

1. GET /auth/session/new — fetch the Rails CSRF token and session cookie.
2. POST /auth/session — log in with email + password (must happen before OAuth authorize).
3. GET /oauth/authorize — receive the one-time authorization code via redirect.
4. POST /oauth/token — exchange the code for a bearer access_token + refresh_token (7-day expiry).

The client then refreshes the token proactively (~60 s before expiry) and reactively on any 401. No bot wall has been observed — the headless flow works directly from Node.

No env vars → clean start: if credentials are not set, the server still starts without error. Auth is deferred to the first tool call, so MCP hosts can complete install-time tool listing before credentials are configured.

Frame model

All data in Skylight is scoped to a frame (the family hub device). On first use the client auto-discovers the single frame on the account. If the account has more than one frame, set SKYLIGHT_FRAME_ID to the frame ID you want. Every tool that reads frame-scoped data accepts an optional frameId arg to override the default.
