CHM To Markdown Converter MCP Server

chm to markdown and vectorDB

The short version

A Python utility for converting Compiled HTML Help (.chm) files into clean Markdown, with built-in support for multiple document types through a profile system.

• Profile-based conversion — — generic profile for any CHM, revit profile for Autodesk Revit API docs
• Auto encoding detection — — handles UTF-8, GB18030, GBK, GB2312, and more via chardet
• Cross-platform 7-Zip detection — — finds 7z/7za/7zz on PATH (Windows, Linux, macOS)
• Flexible CHM structure support — — handles html/ subdirectory, flat, and deeply nested layouts (e.g. DirectX SDK)
• --preserve-structure — — optionally mirrors the CHM's internal folder hierarchy in the output instead of flattening everything into data/
• Code block preservation — — detects language from class names and named divs; supports C#, VB, C++, F#, Python, Java, JS/TS, Bash, SQL, XML, JSON

What it needs from you

• Python 3.10+ - 7-Zip — 7z must be reachable via the default install path or PATH - Windows: installs to C:\Program Files\7-Zip\7z.exe by default, or add to PATH - Linux: sudo apt install p7zip-full - macOS: brew install p7zip
