      "args": ["/path/to/dist/index.js"]
    }
  }
}

import { LeetCodeService } from '@mcpfun/mcp-server-leetcode';

// Initialize the service
const leetcodeService = new LeetCodeService();

// Get daily challenge
const dailyChallenge = await leetcodeService.getDailyChallenge();

// Search problems
const problems = await leetcodeService.searchProblems({
  difficulty: 'MEDIUM',
  tags: 'array+dynamic-programming'
});
