Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
The registry lists no key to fill in.

You need

Common questions

Is Magic Envelope 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 32 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

✉ Magic Envelope

Free invitations and letters: birthdays, weddings, parties, dinners, letters… Pick a ready-made template or build one from typed blocks. Send a link and the guest opens a sealed envelope.

Not an editor. Everything is typed and modular.

Run

pnpm install

pnpm dev # http://localhost:3000

Locally, without any keys, published cards and uploaded images are saved under .data/. Only AI images need a key.

For agents

Everything the app does is available without a browser:

MCP — https://magic-envelope.com/api/mcp (tools: get_catalog, create_letter, get_letter, update_letter)
REST — POST /api/v1/letters, GET|PATCH /api/v1/letters/:id (Authorization: Bearer ), GET /api/v1/catalog
Specs — /api/v1/openapi.json, /api/v1/schema, /llms.txt, docs at /developers

The REST and MCP adapters share one service layer (src/lib/api.server.ts) and validate with the same Zod schemas as the editor.

Native apps (Capacitor 8)

The iOS/Android apps are thin shells around the hosted web app (it needs API routes, so no static export). capacitor.config.ts points the WebView at CAP_SERVER_URL (default https://magic-envelope.com); native-shell/ is only the offline page.

pnpm dev:lan                                   # dev server reachable from your phone

CAP_SERVER_URL=http://192.168.1.20:3000 pnpm cap:android # or cap:ios (opens Android Studio / Xcode)

src/lib/native.ts is the single bridge: each function uses the Capacitor plugin in the app and the web API in the browser.

Function	Native	Browser
`share()`	system share sheet	Web Share, falls back to copying the link
`haptic()`	Taptic/vibration	`navigator.vibrate`
`copy()`	native clipboard	Clipboard API
`pickPhoto()`	camera / photo library	file input (`capture` opens the camera on mobile)
`saveFile()`	write to cache, then share (Files, Calendar…)	download
`onBack()`	Android back button closes sheets / wizard steps	–
deep links	`appUrlOpen` opens `/c/…` inside the app	–

Environment

Variable	Purpose
`AI_GATEWAY_API_KEY`	AI image generation via Vercel AI Gateway (on Vercel, OIDC works without it)
`BLOB_READ_WRITE_TOKEN`	Vercel Blob store for published cards (private) and images (public)
`NEXT_PUBLIC_SITE_URL`	Canonical URL, e.g. `https://magic-envelope.com` (QR codes, OG images)
`IMAGE_MODEL`	Optional override, default `bfl/flux-2-klein-4b` (cheap and fast)

Architecture

src/lib/model.ts        Zod schemas: Card, 15 Block types, kinds, themes, languages

src/lib/blocks.ts block registry (icons, palette, factories) + 24 templates (8 kinds × 3) src/lib/ui.ts app UI copy (always English) src/lib/styles.ts letter styles = design-system tokens (fonts, colors, background, frame, control shape, envelope) + per-letter overrides src/lib/i18n.ts letter languages es · en · fr · pt · it · de (guest-facing copy + presets) src/lib/fields.ts field kinds (phone, email, url, date…): one validator for editor + renderer src/lib/craft.ts seal shapes/marks & envelope geometry/palettes (shared by app and OG image) src/lib/color.ts opaque shading helpers src/lib/themes.ts 6 themes (parchment, midnight, rose, forest, sky, ink) src/lib/actions.ts calendar (.ics / Google), maps, RSVP deep links, music embeds src/lib/drafts.ts drafts in localStorage (no account needed) src/lib/store.server.ts Vercel Blob storage, or .data/ in local dev

Adding a block type

Add a schema in lib/model.ts and include it in the Block union (add a migration there if you change an existing shape).
Add an icon, a palette entry and a factory in lib/blocks.ts, and its label in lib/ui.ts.
Add a renderer case and an isEmpty rule in components/card/blocks.tsx.
Add an editor case in components/editor/block-editor.tsx, using Field with the right field kind.
Add any guest-facing words to lib/i18n.ts.

TypeScript's exhaustive switches flag every step you missed.

Features

Wizard: letter language → style (15 styles: Classic, Elegant, Modern, Playful, Retro) → blank letter (default) or an occasion preset
Style panel in the editor: switch style, customize accent/paper/text colors and title/text fonts, seal (symbol, initials or none), text written on the envelope (supports the guest name)
Preview page mirrors the editor's Link/Image choice and "preview as" guest, and can send directly
App UI is English; each letter has its own language (changeable from the Style panel)
15 blocks: title, text, image, date, place + map, countdown, RSVP (WhatsApp/SMS/email), QR, link, schedule, dress code moodboard (colors, emojis, words, pictures), gifts (IBAN copy / registry), music (Spotify/YouTube/SoundCloud), signature, divider
AI images in 4 styles (storybook, medieval, sketch, photo) and photo upload
Six themes, custom wax-seal glyph, an envelope addressed "To: …"
Guest list: add, paste a list ("Name, phone/email") or pick from contacts; {name} in any text addresses each guest
every guest gets their own link (/c/ ?g= ) — only *their* name is ever sent to their browser
send per guest via their channel (WhatsApp / email / share sheet), track who was sent, copy all links, CSV
RSVP replies carry the guest's name; the envelope is addressed to them
Envelope (link letters): fixed slots holding real blocks — Title (recipient), Text (sender, note, under the seal) and Stamp (postage, 14 perforated stamps) — edited with the same editor, placeholders and rules as the letter; seal in 4 shapes (scalloped, round, flower, octagon) with a vector mark (12 icons, 1–3 initials, a couple "A ♥ J", plain or none), always legible on any wax colour. Styles ship their own envelope (trim + stamp). Guests receive the front, turn it over with a tap, open it with a second; the real letter slides out.
Preview shows exactly what a guest receives: the envelope (replayable) for links, the actual exported PNG for images.
Two outputs from one letter: the interactive link, or flat images (PNG per guest, ZIP for all, print/PDF). Blocks with actions render flat automatically in images, and each can turn its buttons off for the link too.
Share: link, native share sheet, WhatsApp, downloadable QR, print/PDF
Guests get "add to calendar", directions, a live countdown and one-tap RSVP
Installable PWA (iOS/Android home screen), dark-mode chrome, reduced-motion support
Published links are noindex; each card can be re-published from the device that created it
