MCP Website Downloader

Simple MCP server for downloading documentation websites and preparing them for RAG indexing.

Features

Downloads complete documentation sites, well big chunks anyway.
Maintains link structure and navigation, not really. lol
Downloads and organizes assets (CSS, JS, images), but isn't really AI friendly and it all probably needs some kind of parsing or vectorizing into a db or something.
Creates clean index for RAG systems, currently seems to make an index in each folder, not even looked at it.
Simple single-purpose MCP interface, yup.

Installation

Fork and download, cd to the repository.

uv venv
./venv/Scripts/activate
pip install -e .

Put this in your claude_desktop_config.json with your own paths:

   "mcp-windows-website-downloader": {
     "command": "uv",
     "args": [
       "--directory",
       "F:/GithubRepos/mcp-windows-website-downloader",
       "run",
       "mcp-windows-website-downloader",
       "--library",
       "F:/GithubRepos/mcp-windows-website-downloader/website_library"
     ]
   },

Other Usage you don't need to worry about and may be hallucinatory lol:

Start the server:

python -m mcp_windows_website_downloader.server --library docs_library

Use through Claude Desktop or other MCP clients:

result = await server.call_tool("download", {
    "url": "https://docs.example.com"
})

Output Structure

docs_library/
  domain_name/
    index.html
    about.html
    docs/
      getting-started.html
      ...
    assets/
      css/
      js/
      images/
      fonts/
    rag_index.json

Development

The server follows standard MCP architecture:

src/
  mcp_windows_website_downloader/
    __init__.py
    server.py    # MCP server implementation
    core.py      # Core downloader functionality
    utils.py     # Helper utilities

Components

server.py: Main MCP server implementation that handles tool registration and requests
core.py: Core website downloading functionality with proper asset handling
utils.py: Helper utilities for file handling and URL processing

Design Principles

Single Responsibility
- Each module has one clear purpose
- Server handles MCP interface
- Core handles downloading
- Utils handles common operations
Clean Structure
- Maintains original site structure
- Organizes assets by type
- Creates clear index for RAG systems
Robust Operation
- Proper error handling
- Reasonable depth limits
- Asset download verification
- Clean URL/path processing

RAG Index

The rag_index.json file contains:

{
  "url": "https://docs.example.com",
  "domain": "docs.example.com", 
  "pages": 42,
  "path": "/path/to/site"
}
