🚀 SkillCaptain MCP Server

Train Your AI First Engineering Skills - The official Model Context Protocol server that transforms how students learn programming with AI assistance.

🎓 Why This Exists?

The future belongs to AI First Engineers - developers who can effectively collaborate with AI to build better, faster, and smarter. Traditional programming courses teach you to code in isolation, but in the real world, you'll be working alongside AI assistants like Claude, ChatGPT, and Copilot.

This MCP server bridges that gap by giving you:

• ✨ AI-powered learning through Claude Desktop
• 🔄 Real-time feedback on your code submissions
• 📚 Interactive coding practice across 100+ problems
• 🎯 Progressive skill building from basics to advanced DSA

🌟 What Is AI First Engineering?

AI First Engineering means:

1. Prompting your AI to understand problems
2. Collaborating to design solutions
3. Getting instant feedback on code quality
4. Iterating rapidly to improve solutions
5. Building production-ready code faster than ever

You're not just learning to code - you're learning to be 10x more productive.

🚀 Quick Start

Prerequisites

• Node.js 18+ installed
• Claude Desktop app installed

Installation

# Install the MCP server
npm install -g skillcaptain-mcp-server

# Or install locally
npm install skillcaptain-mcp-server

Configuration

Add this to your Claude Desktop MCP configuration file:

MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "skillcaptain": {
      "command": "npx",
      "args": ["-y", "skillcaptain-mcp-server"],
      "env": {}
    }
  }
}

Or use the global installation directly:

{
  "mcpServers": {
    "skillcaptain": {
      "command": "skillcaptain-mcp",
      "args": [],
      "env": {}
    }
  }
}

For local development, use:

{
  "mcpServers": {
    "skillcaptain": {
      "command": "node",
      "args": ["/path/to/skillcaptain-mcp/build/index.js"],
      "env": {}
    }
  }
}

After adding this, restart Claude Desktop.

📖 How to Use It

Once configured, you can interact with SkillCaptain directly through Claude Desktop!

Example Usage

1. Login to Your Account

You: "SkillCaptain, login with my credentials"

Claude: I need your email and password.

You: "hvardhan52@gmail.com, password: welcome"

Claude: ✅ Logged in! Your user ID is 12.

2. Practice Binary Tree Problems

You: "I want to practice binary tree problems"

Claude: Found the "DSA: Binary Tree" course with 9 problems:
1. Day 1: Similar Leaf (Easy) - Check if two binary trees have the same leaf sequence
2. Day 2: Add Row (Medium) - Add a row of nodes at a given depth
3. Day 3: Right Side View (Medium) - Return values visible from the right
...and 6 more!

Which one should we start with?

3. Get Problem Details

You: "Show me Day 1 problem"

Claude: 📋 Problem: Leaf-Similar Trees
Return true if two binary trees have the same leaf value sequence.

Examples:
- Example 1: root1=[3,5,1,6,2,9,8,null,null,7,4], root2=[3,5,1,6,7,4,2,...]
  Output: true (both have leaves [6,7,4,9,8])

Constraints:
- Nodes: 1-200
- Values: 0-200

Hint: Use DFS to collect leaf values, then compare sequences.

4. Write and Test Code Locally

You: "Open a Python file with test cases"

Claude: Created similar_leaf.py with:
- TreeNode class
- build_tree_from_list helper
- 5 test cases (including examples from problem)

Write your solution and run: python similar_leaf.py

5. Submit for Evaluation

You: "Submit the code"

Claude: Code submitted to SkillCaptain!

✅ Status: PASSED
✅ Code Quality: PASSED

Review highlights:
- Clear naming conventions
- Correct DFS implementation
- Good separation of concerns
- Handles edge cases properly

🎉 Solution accepted! Want to try another problem?

🎓 Student Success Stories

From Zero to Hero in 30 Days

Sarah, CS Student: "I went from failing DSA exams to acing interviews by practicing with this AI assistant. The instant feedback helped me learn patterns I was missing."

Mike, Bootcamp Graduate: "Instead of wasting hours debugging, I learned to write better code from day one. The AI taught me coding best practices I would've taken months to figure out."

Priya, Career Switcher: "Coming from non-tech background, having Claude explain problems and review my code was like having a personal tutor 24/7. Landed my first dev job in 6 months!"
