An MCP (Model Context Protocol) server that wraps cn-font-split as agent-callable tools for font subsetting and web-font generation.

Features

• Split TTF/OTF/TTC/WOFF/WOFF2 fonts into optimized web-font subsets (woff2 chunks + CSS)

• Auto-detect font family name from the binary and group output by family

• Batch processing of font directories

• Inspect and summarize generated output

• Cross-platform via WASM backend (no native compilation needed)

Output Layout

split-output/
  <FontFamily>/
    <FontFile>.ttf            # original font preserved
    <FontFile>/               # split output subfolder
      *.woff2
      result.css
      index.html
      reporter.bin

Fonts in the same family are grouped under one directory.
