SealsCrafter MCP Server (印章 · Chinese name seals)

SealsCrafter is a free, remote MCP (Model Context Protocol) server that gives AI assistants the ability to carve a Western name into an authentic Chinese name seal (印章) — real seal script (篆書), a real Chinese name chosen for meaning, returned as a PNG with every character explained.

Why SealsCrafter

• Real seal script, not clip-art — glyphs are vector outlines from the Zhongshan King (中山王) bronze-inscription school, the same engine as the free generator, then rasterized server-side as a red-on-paper seal PNG (朱文 style)
• Real Chinese names, not random transliteration — 53 hand-written name pages (Emma → 艾玛, "wholeness") plus a principled fallback for any other name; every character carries an auspicious meaning
• Meanings included in every call — each tool result explains the characters (pinyin, etymology, classical sources), so the assistant can actually talk about the seal
• Free, no API key, no signup — zero-configuration remote server, generous rate limits for personal use
• Every result links back to the corresponding page on sealscrafter.com

Running your own copy

The production server runs on Cloudflare (Pages Functions, code in sealmaker). This repository contains the standalone Cloudflare Worker version — same rendering pipeline (opentype.js glyph outlines → SVG seal face → resvg-wasm PNG), deployable with:

npm install
npx wrangler deploy

Requires the fonts under assets/fonts/ (JFZSKSeal V3.5, OFL licensed; Chong Xi Small Seal, OFL licensed). Seal script fonts are the artwork here — if you fork for a commercial product, review their OFL terms.

Privacy

The server is stateless: it renders and answers, it does not store your names or any account.

License

MIT (code). Fonts keep their own OFL licenses (see assets/fonts/).
