Magic Envelope

Magic Envelope lets your agent create and send illustrated digital invitations end to end: every guest gets their own personal link, with their name printed on a sealed envelope and inside the letter. No account, no API key - the agent calls a free REST API (or connects the MCP server) and gets back per-guest links and preview images.

Make invitations for birthdays, weddings, parties, baby showers, dinners, graduations and any event, plus personal letters. 15 visual styles (classic parchment to 8-bit pocket), 6 languages (es, en, fr, pt, it, de), and blocks for date, place with map, countdown, schedule, dress code, gifts, music, QR and RSVP via WhatsApp, SMS or email. Guests answer Yes/Maybe/No right in the letter; the host reads the answers back through the API.

The skill teaches your agent the whole flow: picking style and preset, personalizing each guest's name with {name} placeholders, creating the letter in one request, delivering each guest their own link, and editing or deleting letters later. Includes a block reference with field examples and two complete request examples (a Spanish birthday dinner and an English wedding).

Known limitations:

• Requires internet access.
• Tapping an RSVP answer also opens the guest's WhatsApp, SMS or email app with a prefilled message to the host.
• Dates are venue-local time (no timezones).
