Turn Your AI Assistant Into a LeetCode Power User

Stop switching between Claude and LeetCode tabs. This MCP server gives your AI direct access to LeetCode's entire problem database, user profiles, and contest data—making your coding interview prep exponentially more intelligent.

The Problem with Manual LeetCode Grinding

You're probably doing this: manually searching for problems, copying descriptions into Claude, asking for hints, then going back to implement. It's inefficient and breaks your flow. You lose context switching between tools, and your AI can't see your actual progress or recommend what to tackle next.

What This Changes

Instead of feeding problems to your AI piecemeal, your assistant can now:

• Analyze your solving patterns by pulling your submission history and identifying weak spots
• Recommend targeted practice based on your contest rankings and performance gaps
• Generate personalized study plans using your actual LeetCode data, not generic advice
• Provide contextual hints while knowing exactly which problems you've attempted
• Track daily challenges and suggest similar problems when you're stuck

Real Workflow Improvements

Morning Prep Session:

You: "What should I focus on today?"
Claude: *pulls your profile* "You've solved 12/50 dynamic programming problems with a 65% success rate. Today's daily challenge is a medium DP problem—perfect timing. Want me to walk through similar problems you haven't seen?"

Contest Strategy:

You: "How do I improve my contest ranking?"
Claude: *analyzes your contest history* "You consistently solve first two problems fast but struggle with graph problems under pressure. Here are 5 medium graph problems similar to recent contest questions..."

Targeted Practice:

You: "Find me array problems I haven't solved"
Claude: *searches problem database* "Here are 10 unsolved array problems ranked by difficulty and similar to ones you've successfully completed..."

Integration That Actually Works

Works seamlessly with Claude Desktop—add one JSON config block and you're done. No API keys, no authentication headaches. The server handles LeetCode's GraphQL API complexity so your AI can focus on helping you code better.

{
  "mcpServers": {
    "leetcode": {
      "command": "mcp-server-leetcode"
    }
  }
}

You can also use it programmatically in your own tools:

const leetcode = new LeetCodeService();
const problems = await leetcode.searchProblems({
  difficulty: 'MEDIUM',
  tags: 'dynamic-programming+array'
});

What's Actually Included

Problem Tools:

• Daily challenge retrieval (never miss the streak)
• Problem search by tags, difficulty, company
• Complete problem details with constraints and examples

User Analytics:

• Profile stats and submission history
• Contest ranking analysis
• Progress tracking across problem categories

Contest Intelligence:

• Contest details and historical data
• Ranking comparisons and trend analysis

Resource Access:

• Direct URI-based problem access (leetcode://problem/two-sum)
• User profile resources with submission filtering
• Cached responses for fast repeated queries

Why This Beats DIY Solutions

You could spend hours setting up LeetCode's GraphQL API yourself, handling authentication, implementing caching, and parsing responses. Or you could install this, configure Claude in 30 seconds, and immediately start having smarter coding conversations.

The server handles all the complexity: API rate limiting, response caching, error handling, and MCP protocol compliance. You get enterprise-grade LeetCode integration without the enterprise setup time.

Getting Started

Install globally and run:

npm install -g @mcpfun/mcp-server-leetcode
mcp-server-leetcode

Or use Smithery for automatic Claude Desktop setup:

npx -y @smithery/cli install @doggybee/mcp-server-leetcode --client claude

Your AI assistant just got a lot smarter about helping you land that next role.
