Wikipedia MCP Server

A Model Context Protocol (MCP) server that retrieves information from Wikipedia to provide context to Large Language Models (LLMs). This tool helps AI assistants access factual information from Wikipedia to ground their responses in reliable sources.

Overview

The Wikipedia MCP server provides real-time access to Wikipedia information through a standardized Model Context Protocol interface. This allows LLMs to retrieve accurate and up-to-date information directly from Wikipedia to enhance their responses.

Features

• Search Wikipedia: Find articles matching specific queries with enhanced diagnostics
• Retrieve Article Content: Get full article text with all information
• Article Summaries: Get concise summaries of articles
• Section Extraction: Retrieve specific sections from articles
• Link Discovery: Find links within articles to related topics
• Related Topics: Discover topics related to a specific article
• Multi-language Support: Access Wikipedia in different languages by specifying the --language or -l argument when running the server (e.g., wikipedia-mcp --language ta for Tamil).
• Country/Locale Support: Use intuitive country codes like --country US, --country China, or --country TW instead of language codes. Automatically maps to appropriate Wikipedia language variants.
• Language Variant Support: Support for language variants such as Chinese traditional/simplified (e.g., zh-hans for Simplified Chinese, zh-tw for Traditional Chinese), Serbian scripts (sr-latn, sr-cyrl), and other regional variants.
• Optional caching: Cache API responses for improved performance using --enable-cache
• Modern MCP Transport Support: Supports stdio, http, and streamable-http (with legacy sse compatibility).
• Optional MCP Transport Auth: Secure network transports with --auth-mode static or --auth-mode jwt.
• Google ADK Compatibility: Fully compatible with Google ADK agents and other AI frameworks that use strict function calling schemas

Installation

Using pipx (Recommended for Claude Desktop)

The best way to install for Claude Desktop usage is with pipx, which installs the command globally:

# Install pipx if you don't have it
pip install pipx
pipx ensurepath

# Install the Wikipedia MCP server
pipx install wikipedia-mcp

This ensures the wikipedia-mcp command is available in Claude Desktop's PATH.

Installing via Smithery

To install wikipedia-mcp for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @Rudra-ravi/wikipedia-mcp --client claude

From PyPI (Alternative)

You can also install directly from PyPI:

pip install wikipedia-mcp

Note: If you use this method and encounter connection issues with Claude Desktop, you may need to use the full path to the command in your configuration. See the Configuration section for details.

Using a virtual environment

# Create a virtual environment
python3 -m venv venv

# Activate the virtual environment
source venv/bin/activate

# Install the package
pip install git+https://github.com/rudra-ravi/wikipedia-mcp.git

From source

# Clone the repository
git clone https://github.com/rudra-ravi/wikipedia-mcp.git
cd wikipedia-mcp

# Create a virtual environment
python3 -m venv wikipedia-mcp-env
source wikipedia-mcp-env/bin/activate

# Install in development mode
pip install -e .

Usage

Running the server

# If installed with pipx
wikipedia-mcp

# If installed in a virtual environment
source venv/bin/activate
wikipedia-mcp

# Specify transport protocol (default: stdio)
wikipedia-mcp --transport stdio  # For Claude Desktop
wikipedia-mcp --transport http --host 0.0.0.0 --port 8080 --path /mcp
wikipedia-mcp --transport streamable-http --host 0.0.0.0 --port 8080 --path /mcp
wikipedia-mcp --transport sse    # Legacy compatibility transport

# Specify language (default: en for English)
wikipedia-mcp --language ja  # Example for Japanese
wikipedia-mcp --language zh-hans  # Example for Simplified Chinese
wikipedia-mcp --language zh-tw    # Example for Traditional Chinese (Taiwan)
wikipedia-mcp --language sr-latn  # Example for Serbian Latin script

# Specify country/locale (alternative to language codes)
wikipedia-mcp --country US        # English (United States)
wikipedia-mcp --country China     # Chinese Simplified
wikipedia-mcp --country Taiwan    # Chinese Traditional (Taiwan)  
wikipedia-mcp --country Japan     # Japanese
wikipedia-mcp --country Germany   # German
wikipedia-mcp --country france    # French (case insensitive)

# List all supported countries
wikipedia-mcp --list-countries

# Optional: Specify host/port/path for network transport (use 0.0.0.0 for containers)
wikipedia-mcp --transport http --host 0.0.0.0 --port 8080 --path /mcp

# Optional: Enable caching
wikipedia-mcp --enable-cache

# Optional: Use Personal Access Token to avoid rate limiting (403 errors)
wikipedia-mcp --access-token your_wikipedia_token_here

# Or set via environment variable
export WIKIPEDIA_ACCESS_TOKEN=your_wikipedia_token_here
wikipedia-mcp

# Optional: Secure incoming MCP network requests with static bearer token
wikipedia-mcp --transport http --auth-mode static --auth-token your_mcp_token --host 0.0.0.0 --port 8080

# Optional: Secure incoming MCP network requests with JWT validation
wikipedia-mcp --transport http --auth-mode jwt --auth-jwks-uri https://issuer/.well-known/jwks.json --auth-issuer https://issuer

# Security note: prefer http/streamable-http + auth-mode for exposed network transport.

# Combine options
wikipedia-mcp --country Taiwan --enable-cache --access-token your_wikipedia_token --transport http --path /mcp --port 8080

### Docker/Kubernetes

When running inside containers, bind the HTTP MCP server to all interfaces and map
the container port to the host or service:

```bash
# Build and run with Docker
docker build -t wikipedia-mcp .
docker run --rm -p 8080:8080 wikipedia-mcp --transport http --host 0.0.0.0 --port 8080 --path /mcp

Kubernetes example (minimal):

apiVersion: apps/v1
kind: Deployment
metadata:
  name: wikipedia-mcp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: wikipedia-mcp
  template:
    metadata:
      labels:
        app: wikipedia-mcp
    spec:
      containers:
        - name: server
          image: your-repo/wikipedia-mcp:latest
          args: ["--transport", "http", "--host", "0.0.0.0", "--port", "8080", "--path", "/mcp"]
          ports:
            - containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: wikipedia-mcp
spec:
  selector:
    app: wikipedia-mcp
  ports:
    - name: http
      port: 8080
      targetPort: 8080

### Configuration for Claude Desktop

Add the following to your Claude Desktop configuration file:

**Option 1: Using command name (requires `wikipedia-mcp` to be in PATH)**
```json
{
  "mcpServers": {
    "wikipedia": {
      "command": "wikipedia-mcp"
    }
  }
}

Option 2: Using full path (recommended if you get connection errors)

{
  "mcpServers": {
    "wikipedia": {
      "command": "/full/path/to/wikipedia-mcp"
    }
  }
}

Option 3: With country/language specification

{
  "mcpServers": {
    "wikipedia-us": {
      "command": "wikipedia-mcp",
      "args": ["--country", "US"]
    },
    "wikipedia-taiwan": {
      "command": "wikipedia-mcp", 
      "args": ["--country", "TW"]
    },
    "wikipedia-japan": {
      "command": "wikipedia-mcp",
      "args": ["--country", "Japan"]
    }
  }
}

To find the full path, run: which wikipedia-mcp
