const server = new MCPServer({
  name: 'my-custom-tool',
  version: '1.0.0'
});

// Register tool
server.tool('analyze-code', {
  description: 'Analyze code complexity',
  parameters: {
    type: 'object',
    properties: {
      code: { type: 'string' },
      language: { type: 'string' }
    }
  }
}, async ({ code, language }) => {
  // Implement code analysis logic
  return {
    complexity: calculateComplexity(code),
    suggestions: generateSuggestions(code, language)
  };
});

server.start();

Best Practices​

1. MCP Selection Principles​

# ✅ Choose mature and stable MCPs
Prioritize official or community-widely used extensions

# ✅ Evaluate security
Review MCP permission requirements and data handling methods

# ✅ Consider maintenance costs
Choose projects with active maintenance

2. Configuration Management​

{
  "environments": {
    "development": {
      "mcps": ["github", "local-db", "dev-tools"]
    },
    "production": {
      "mcps": ["github", "production-db", "monitoring"]
    }
  }
}

3. Performance Optimization​
