Overview

Description from the maker (original English)

Skylight Calendar for Claude — family events, chores, and rewards.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Docs, sheets & office work
  • You need to fill in: SKYLIGHT_REFRESH_TOKEN, SKYLIGHT_PASSWORD, SKYLIGHT_APPLE_APP_PASSWORD

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: SKYLIGHT_REFRESH_TOKEN, SKYLIGHT_EMAIL, SKYLIGHT_PASSWORD, SKYLIGHT_FRAME_ID, SKYLIGHT_NAME, SKYLIGHT_TOKEN_CACHE, SKYLIGHT_TOKEN_FILE, SKYLIGHT_BASE_URL, SKYLIGHT_APPLE_APP_PASSWORD, SKYLIGHT_APPLE_ID, SKYLIGHT_UPLOAD_DIR

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • SKYLIGHT_REFRESH_TOKEN secret env
    An OAuth refresh token you already hold. Supply this and no password is needed — the login is skipped entirely.
  • SKYLIGHT_EMAIL env
    Skylight account email. Pair with SKYLIGHT_PASSWORD for direct login. Needed only if you are not supplying SKYLIGHT_REFRESH_TOKEN.
  • SKYLIGHT_PASSWORD secret env
    Skylight account password — required iff SKYLIGHT_EMAIL is set. Needed only if you are not supplying SKYLIGHT_REFRESH_TOKEN.
  • SKYLIGHT_FRAME_ID env
    Optional: pick a specific Skylight frame when the account has more than one.
  • SKYLIGHT_NAME env
    Friendly account name used in startup logs.
  • SKYLIGHT_TOKEN_CACHE env
    Set to false to disable the on-disk token cache and re-authenticate on every process start. Defaults to enabled.
  • SKYLIGHT_TOKEN_FILE env
    Absolute path for the token cache file. Defaults to $MCP_DATA_DIR/.skylight-mcp/tokens.json.
  • SKYLIGHT_BASE_URL env
    Override the API base (default https://app.ourskylight.com/api). The auth origin is derived from it, so pointing this elsewhere moves the login flow too — and the new host must be added to the regist…
  • SKYLIGHT_APPLE_APP_PASSWORD secret env
    Optional: an app-specific password from appleid.apple.com, used only by skylight_link_apple_calendar. Env-only by design — the tool takes no password argument, so the credential never passes through…
  • SKYLIGHT_APPLE_ID env
    Optional: the Apple ID email skylight_link_apple_calendar links; the tool's email argument overrides it.
  • SKYLIGHT_UPLOAD_DIR env
    Optional: directories that the photo-upload, event-import-from-photo and avatar tools may read files from (several separated by ':', or ';' on Windows; '~' allowed). Any other path is refused. Unset:…

Common questions

Is Skylight MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SKYLIGHT_REFRESH_TOKEN, SKYLIGHT_PASSWORD, SKYLIGHT_APPLE_APP_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.6.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

skylight-mcp

MCP server for Skylight Calendar — 115 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 …".

MCP protocol support

The server uses the official TypeScript SDK v2 and supports the stateless 2026-07-28 protocol revision over stdio. Clients can discover and call tools without an initialization handshake. Existing clients can still use the 2025-11-25 handshake.

The transport remains stdio. A host can expose it over authenticated HTTP. This package does not open a network listener.

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).

OAuth redirects stay on the authentication origin. Relative redirects resolve against the current URL. The configured callback supplies the authorization code without receiving a request or session cookie. Unexpected destinations fail without including the redirect URL in the error.

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.

Using the auth helpers from your own code

The package also exports Skylight's session login and refresh, so a separate program can authenticate without copying src/:

import { login, refresh } from 'skylight-mcp/auth';

const tokens = await login({ authBaseUrl: 'https://app.ourskylight.com', email: process.env.SKYLIGHT_EMAIL!, password: process.env.SKYLIGHT_PASSWORD!, }); // Skylight rotates refresh tokens: store the one each call returns. const next = await refresh({ authBaseUrl: 'https://app.ourskylight.com', refreshToken: tokens.refreshToken });

This is the only library entry point; everything else in the package is the MCP server. It is ESM-only and ships type declarations.

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.
