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.

Test Configuration

The project uses pytest.ini for test configuration:

[pytest]
markers =
    integration: marks tests as integration tests (may require network access)
    slow: marks tests as slow running

testpaths = tests
addopts = -v --tb=short

Continuous Integration

All tests are designed to:

• Run reliably in CI/CD environments
• Handle network failures gracefully
• Provide clear error messages
• Cover edge cases and error conditions

Adding New Tests

When contributing new features:

1. Add unit tests for new functionality
2. Include both success and failure scenarios
3. Mock external dependencies (Wikipedia API)
4. Add integration tests for end-to-end validation
5. Follow existing test patterns and naming conventions

Troubleshooting

Common Issues

• Connection Error: Ensure the command in claude_desktop_config.json is correct
• Article Not Found: Check the exact spelling of article titles
• Rate Limiting: Wikipedia API has rate limits; consider adding delays between requests
• Large Articles: Some Wikipedia articles are very large and may exceed token limits

Understanding the Model Context Protocol (MCP)

The Model Context Protocol (MCP) is not a traditional HTTP API but a specialized protocol for communication between LLMs and external tools. Key characteristics:

• Uses stdio (standard input/output) or SSE (Server-Sent Events) for communication
• Designed specifically for AI model interaction
• Provides standardized formats for tools, resources, and prompts
• Integrates directly with Claude and other MCP-compatible AI systems

Claude Desktop acts as the MCP client, while this server provides the tools and resources that Claude can use to access Wikipedia information.
