MCP server for [Skylight Calendar](https://www.ourskylight.com) — 114 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), photo/video upload, and frame/device/account settings + calendar + member management (read+write, incl. preset and custom-photo avatars).

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. Configure it with `SKYLIGHT_REFRESH_TOKEN` if you already hold a token, or `SKYLIGHT_EMAIL` + `SKYLIGHT_PASSWORD` to log in for one.

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` — send an S256 PKCE `code_challenge` (the server requires it) and receive the one-time authorization code via redirect.
4. `POST /oauth/token` — exchange the code plus the matching `code_verifier` for a bearer `access_token` + `refresh_token` (currently a 24-hour expiry; the client reads the returned `expires_in` rather than assuming).

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.

## Configuration

### Required — one of these two

**A refresh token you already hold** (preferred: scoped, revocable, and it never
touches the rate-limited login endpoint):

```
SKYLIGHT_REFRESH_TOKEN=your-refresh-token
```

**Or the login pair**, which mints one for you:

```
SKYLIGHT_EMAIL=you@example.com
SKYLIGHT_PASSWORD=your-password
```

Setting both is also valid, and is the most robust configuration: the token is
used first, and if it has expired the login quietly mints a replacement. With a
token alone, an expired token is reported as expired — the server says so
plainly rather than claiming it is unconfigured.

### Optional

| Env var | Default | Purpose |
|---|---|---|
| `SKYLIGHT_FRAME_ID` | auto-discovered | Force a specific frame when the account has multiple |
| `SKYLIGHT_NAME` | *(none)* | Friendly label used in startup logs |
| `SKYLIGHT_BASE_URL` | `https://app.ourskylight.com/api` | Override the API base URL |

Treat `.env` like a password file — it is gitignored, do not commit it.

### Token cache

After the first login the OAuth token pair is cached at
`$MCP_DATA_DIR/.skylight-mcp/tokens.json` (falling back to `$HOME`), written
`0600`. A later start reuses it instead of re-running the four-step login —
which matters because Skylight's login endpoint rate-limits, and a hosted
server that scales to zero cold-starts constantly.

Only the tokens are written; your email and password stay in the environment.
A cached token that has expired is refreshed rather than re-logged-in, and a
refresh token the server rejects falls back to a fresh login, so a stale file
cannot lock you out.

The cache is bound to whichever credential minted it — the password pair, or the
supplied `SKYLIGHT_REFRESH_TOKEN`. Rotate that credential, or point the server at
a different account, and the cached token is discarded rather than kept in play.
Only a salted digest is stored; no email, password or supplied token reaches the
file.

Set `SKYLIGHT_TOKEN_CACHE=false` to turn it off and log in on every start, or
`SKYLIGHT_TOKEN_FILE` to put the cache somewhere specific.

If a write fails (read-only or full data dir) the server logs to stderr and
keeps working on the in-memory token — only the next start pays for it.

## Local dev

```
npm install
npm run build
npm test
npm run dev   # requires .env with credentials
```

Tests: vitest, 100% line/branch/function/statement coverage enforced. All tests are mocked — no network calls in CI.
