Bracker

An MCP (Model Context Protocol) server that gamifies your development process by tracking builds, posts, calculating XP, and generating "build in public" content with social media themed levels.

🎮 Features

• XP System: Earn XP from tokens burned, lines changed, and social media posts
• Social Media Levels: Rise from Lurker to Legend with realistic progression
• Post Gates: Level advancement requires posting your progress publicly
• Streak Bonuses: Get XP multipliers for consecutive days of building
• Tweet Generation: Auto-draft "build in public" content with level context
• Simple Storage: JSONL builds log + JSON stats

📈 XP Calculation

• 1 XP per 100 tokens burned in AI sessions
• 1 XP per 10 lines changed in commits
• 50 XP per social media post (encourages building in public)
• Streak multiplier: Up to 2x for consecutive building days
• Steeper curve: Level² × 75 XP required (Legend takes ~6 months of daily building)

🏆 Social Media Themed Levels

• 1-5: 🫥 Lurker - "Nobody. Zero followers energy."
• 6-10: 🌱 Seedling - "First commits, first posts. Sprouting."
• 11-15: 🔨 Maker - "Actually building stuff. People notice."
• 16-20: 📢 Broadcaster - "Posting regularly. Small following."
• 21-25: 🔥 Hot Take - "Content hits different. Growing fast."
• 26-30: ⚡ Shipper - "Ships weekly. Known in the scene."
• 31-35: 🏗️ Architect - "People study your repos."
• 36-40: 🎯 Influencer - "Have you seen what X built?"
• 41-45: 👑 Thought Leader - "Industry talks. Podcast invites."
• 46-50: 🦄 Unicorn - "Everyone knows your name."
• 51+: 🌍 Legend - "Changed the game."

🚪 Post Gates - Build AND Share

You can't advance past certain tiers without posting publicly:

• Level 1-10: No posting required (just build)
• Level 11-20: Need 1 post per level to unlock (10 total posts)
• Level 21-30: Need 2 posts per level to unlock (20 more posts)
• Level 31+: Need 3 posts per level to unlock

Why? Because the best builders share their journey. Level gates encourage authentic building in public.

🚀 Installation

1. Install the MCP server

npm install -g bracker

Or clone and install locally:

git clone <this-repo>
cd bracker
npm install
npm link  # Makes 'bracker' available globally

2. Add to Claude Code config

Add this to your ~/.claude/settings.json under mcpServers:

{
  "mcpServers": {
    "bracker": {
      "command": "bracker",
      "args": []
    }
  }
}

3. Install git hook (optional)

For automatic build logging on pushes:

# In your project directory
cp /path/to/bracker/hooks/post-push.sh .git/hooks/post-push
chmod +x .git/hooks/post-push

Or use the installer script:

# From the bracker directory
./hooks/install-hook.sh /path/to/your/project

📊 Storage

Data is stored in ~/.bracker/:

• builds.jsonl: Build events (one JSON object per line)
• stats.json: Aggregate statistics

🔍 Testing

Test the MCP server:

echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | bracker

Should return the available tools.

🤖 Usage with Claude Code

Once configured, Claude Code can call bracker tools:

Log a build: ``` Log this build:

• Repo: my-app
• Changes: Added auth system, 150 lines
• Tokens used: 2500
• Commit: "feat: implement JWT authentication"

**Log a social media post:**

I just tweeted about my progress: https://twitter.com/user/status/123456789 ```

Get current stats: `` What's my current level and progress? ``

Generate a tweet: `` Suggest a tweet about today's work (polished style) ``

Claude will track your builds, posts, calculate XP, warn about post gates, and help you build in public!

💡 Pro Tips

1. Session Files: Create .claude_session in your project root with conversation summary and token count for automatic hook detection
2. Multiple Repos: Each repo contributes to the same XP pool
3. Streak Building: Code every day for maximum XP multipliers
4. Tweet Styles: Use different styles for different audiences

🛠️ Development

# Clone the repo
git clone <this-repo>
cd bracker

# Install dependencies
npm install

# Test locally
npm test

# Make changes and test
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | node index.js
