MediaWiki MCP server

The MediaWiki MCP Server provides a powerful toolset that allows AI assistants like Claude to interact with MediaWiki instances. It communicates with the MediaWiki API using nodemw to retrieve page content and perform various wiki-related functions.

Features

• Page Content Retrieval: Fetch HTML content and metadata from wiki pages
• Wiki Search: Search for pages based on keywords
• Category Information: Retrieve category information for pages
• Link Analysis: Extract internal links from pages

Prerequisites

• Node.js 18 or higher
• npm or yarn

Installation

To install the MediaWiki MCP Server, you need to have Node.js and npm or yarn installed on your system. The server can be installed and run using npm:

npm install @harugon/mediawiki-mcp-server

Configuration

The server is configured through environment variables. Here are the available options:

Environment Variable	Required	Default Value	Description
MEDIAWIKI_PROTOCOL	No	https	Communication protocol for MediaWiki server
MEDIAWIKI_SERVER	Yes	-	MediaWiki server hostname (e.g., ja.wikipedia.org)
MEDIAWIKI_PATH	No	/w	Path to MediaWiki
MEDIAWIKI_USERNAME	No	-	Username for login
MEDIAWIKI_PASSWORD	No	-	Password for login
MEDIAWIKI_USER_AGENT	No	MediaWiki-MCP-Server/1.0	User agent for API requests
MEDIAWIKI_CONCURRENCY	No	3	Connection concurrency limit
DEBUG	No	0	Debug mode (1 to enable)

Usage with Claude

Configuration Example

You can integrate the MediaWiki MCP Server with Claude by adding the following configuration to your claude_desktop_config.json file:

{
  "mcpServers": {
    "mediawiki": {
      "command": "npm",
      "args": ["@harugon/mediawiki-mcp-server"],
      "env": {
        "MEDIAWIKI_PROTOCOL": "https",
        "MEDIAWIKI_SERVER": "ja.wikipedia.org",
        "MEDIAWIKI_PATH": "/w",
        "MEDIAWIKI_USER_AGENT": "MediaWiki-MCP-Server/1.0",
        "MEDIAWIKI_CONCURRENCY": "3",
        "DEBUG": "1"
      }
    }
  }
}

This configuration sets up Claude to use the MediaWiki MCP Server to access the Japanese Wikipedia. You can customize the environment variables to connect to different MediaWiki instances.

Limitations

There are some known limitations when using the MediaWiki MCP Server:

• The server may fail to retrieve very large articles (chunking functionality needed)
• Functionality is limited by the capabilities of the nodemw dependency

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mediawiki" '{"command":"npm","args":["@harugon/mediawiki-mcp-server"],"env":{"MEDIAWIKI_PROTOCOL":"https","MEDIAWIKI_SERVER":"ja.wikipedia.org","MEDIAWIKI_PATH":"/w","MEDIAWIKI_USER_AGENT":"MediaWiki-MCP-Server/1.0","MEDIAWIKI_CONCURRENCY":"3","DEBUG":"1"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mediawiki": {
            "command": "npm",
            "args": [
                "@harugon/mediawiki-mcp-server"
            ],
            "env": {
                "MEDIAWIKI_PROTOCOL": "https",
                "MEDIAWIKI_SERVER": "ja.wikipedia.org",
                "MEDIAWIKI_PATH": "/w",
                "MEDIAWIKI_USER_AGENT": "MediaWiki-MCP-Server/1.0",
                "MEDIAWIKI_CONCURRENCY": "3",
                "DEBUG": "1"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "mediawiki": {
            "command": "npm",
            "args": [
                "@harugon/mediawiki-mcp-server"
            ],
            "env": {
                "MEDIAWIKI_PROTOCOL": "https",
                "MEDIAWIKI_SERVER": "ja.wikipedia.org",
                "MEDIAWIKI_PATH": "/w",
                "MEDIAWIKI_USER_AGENT": "MediaWiki-MCP-Server/1.0",
                "MEDIAWIKI_CONCURRENCY": "3",
                "DEBUG": "1"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
