lpc-character-mcp
Generates random Universal LPC spritesheet characters as full animation PNGs, compositing real sprite layers via a Cloudflare Worker with browser rendering.
README
lpc-character-mcp (Cloudflare Worker)
A hosted MCP server that randomly generates Universal LPC Spritesheet Character Generator characters and renders each as a full animation spritesheet PNG — no local install, no AI image model, just real sprite layers composited on a canvas.
Runs entirely on Cloudflare Workers + Browser Rendering (headless
Chromium via @cloudflare/puppeteer), with the ~141k sprite assets and every
generated character stored in R2.

Storage
Generated characters live under the generated/ prefix in R2 and are
auto-deleted after 30 days by a bucket lifecycle rule
(expire-generated-30d).
