Example Prompts

Once the server is running and configured with Claude Desktop, you can use prompts like:

  • "Tell me about quantum computing using the Wikipedia information."
  • "Summarize the history of artificial intelligence based on Wikipedia."
  • "What does Wikipedia say about climate change?"
  • "Find Wikipedia articles related to machine learning."
  • "Get me the introduction section of the article on neural networks from Wikipedia."

MCP Resources

The server also provides MCP resources (similar to HTTP endpoints but for MCP):

  • search/{query}: Search Wikipedia for articles matching the query
  • article/{title}: Get the full content of a Wikipedia article
  • summary/{title}: Get a summary of a Wikipedia article
  • sections/{title}: Get the sections of a Wikipedia article
  • links/{title}: Get the links in a Wikipedia article

Development

Local Development Setup

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

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

Project Structure

  • wikipedia_mcp/: Main package
    • __main__.py: Entry point for the package
    • server.py: MCP server implementation
    • wikipedia_client.py: Wikipedia API client
    • api/: API implementation
    • core/: Core functionality

Test Structure

The test suite is organized in the tests/ directory with the following test files:

  • test_basic.py: Basic package functionality tests
  • test_cli.py: Command-line interface and transport tests
  • test_server_tools.py: Comprehensive tests for all MCP tools and Wikipedia client functionality

Running Tests

Run All Tests
# Install test dependencies
pip install -r requirements-dev.txt

# Run all tests
python -m pytest tests/ -v

# Run tests with coverage
python -m pytest tests/ --cov=wikipedia_mcp --cov-report=html
Run Specific Test Categories
# Run only unit tests (excludes integration tests)
python -m pytest tests/ -v -m "not integration"

# Run only integration tests (requires internet connection)
python -m pytest tests/ -v -m "integration"

# Run specific test file
python -m pytest tests/test_server_tools.py -v

Test Categories

Unit Tests
  • WikipediaClient Tests: Mock-based tests for all client methods
    • Search functionality
    • Article retrieval
    • Summary extraction
    • Section parsing
    • Link extraction
    • Related topics discovery
  • Server Tests: MCP server creation and tool registration
  • CLI Tests: Command-line interface functionality
Integration Tests
  • Real API Tests: Tests that make actual calls to Wikipedia API
  • End-to-End Tests: Complete workflow testing

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.
