ZIM MCP Server

ZIM (Zeno IMproved) is a file format developed by the nonprofit organization Kiwix, designed specifically for offline storage and access to Wikipedia and other large reference content. The ZIM format supports high compression rates and fast searching, enabling entire Wikipedia content to be compressed into relatively small files for convenient storage and use, especially in environments without internet connectivity.

ZIM MCP Server provides large language models with the ability to directly access and search content within ZIM files, allowing people to use local AI models for question answering and information retrieval from these offline knowledge resources, even without network access.

About Kiwix

Kiwix is a nonprofit organization dedicated to making online knowledge content (especially Wikipedia, TED talks, etc.) accessible offline. Kiwix has developed tools for creating, viewing, and searching ZIM files, through which people can package large amounts of online knowledge resources into ZIM files for local access. The Kiwix project is particularly important for developing countries and regions without internet connectivity, as it enables people in these areas to access rich knowledge resources, promoting the dissemination of knowledge and equal educational opportunities.

Installation

1. Clone the Repository

git clone https://github.com/ThinkInAI-Hackathon/zim-mcp-server.git

2. Install uv

• On Windows:
  • If you have not set execution policy before, run:

    powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

3. Install Dependencies

cd path\to\zim-mcp-server   # (e.g., D:\zim-mcp-server)
uv sync

4. Prepare ZIM Files

Download ZIM files (e.g., Wikipedia, Wiktionary, etc.) from the Kiwix Library and place them in a directory, e.g.,

path\to\zim\files   # (e.g., D:\ZIM)

Configuration for Claude Desktop

The configuration for Claude Desktop requires the local path to your cloned repository.

Add the following to your claude_desktop_config.json (replace the paths with your actual local paths):

"zim-mcp-server": {
  "command": "uv",
  "args": [
    "--directory",
    "path\\to\\zim-mcp-server",   // e.g., D:\\zim-mcp-server
    "run",
    "server.py",
    "path\\to\\zim\\files"      // e.g., D:\\ZIM
  ]
}

• "path\\to\\zim-mcp-server": Local path to your cloned zim-mcp-server repository (e.g., D:\zim-mcp-server).
• "path\\to\\zim\\files": Directory containing your ZIM files (e.g., D:\ZIM).

Claude Desktop will recognize the server only after this configuration.

## Content

Artificial intelligence (AI) is intelligence demonstrated by machines, as opposed to intelligence displayed by humans or by other animals. Examples of specific artificial intelligence applications include expert systems, natural language processing, and computer vision.

Leading AI textbooks define the field as the study of "intelligent agents": any system that perceives its environment and takes actions that maximize its chance of achieving its goals. Some popular accounts use the term "artificial intelligence" to describe machines that mimic "cognitive" functions that humans associate with the human mind, such as "learning" and "problem solving".
