Tools
| Tool | Description | Behaviour |
|---|---|---|
| create_letter | Create and publish an invitation or letter. Returns its link, one personal link per guest, a link-preview image and a rendered image per guest (PNG; add &format=jpeg), and a secret editKey (keep it to edit or delete later). Use {name} in texts to address each guest. Dates are local: "2026-11-14" (whole day) or "2026-11-14T18:00". | Not declared |
| delete_letter | Delete a letter for good (needs its editKey): its links stop working, and guest names, RSVP answers and images are erased. | Not declared |
| get_catalog | Styles, occasion presets, block types (with examples), envelope slots, stamps and seal options. Call this first to compose a letter. | Not declared |
| get_letter | Read a letter you created (needs its editKey): its content, links, images, and the guests' RSVP answers (yes / maybe / no, plus who hasn't answered). | Not declared |
| update_letter | Change a letter. Only the fields you send change (lang, style… are kept). Links keep working. `guests` replaces the list but keeps each existing guest's id and link (matched by id, then by name); `addGuests` appends without touching anyone else. | Not declared |
