What is Code Guardian Studio?

Code Guardian Studio (CCG) is an MCP server that transforms Claude Code into an intelligent refactoring assistant. It scans your codebase, finds hotspots, generates optimization reports, and helps you refactor safely.

Key Stats (from dogfooding CCG on itself)

Metric	Value
Lines Analyzed	68,000
Files Scanned	212
Hotspots Found	20
Analysis Time	< 1 minute

3-Minute Quickstart

Get your first code analysis in one command:

# Install globally
npm install -g codeguardian-studio

# Run quickstart (auto-initializes + analyzes your code)
ccg quickstart

That's it! The quickstart command will:

• Initialize CCG in your project
• Scan your codebase
• Analyze code complexity and hotspots
• Generate a detailed markdown report

Open the generated report and start fixing hotspots (highest score first).

Want more control? See Manual Setup or read the full Quickstart Guide.

Installation Requirements

CCG uses better-sqlite3 (native SQLite bindings) which requires build tools on your system:

Linux (Ubuntu/Debian)

sudo apt-get update
sudo apt-get install build-essential python3
npm install -g codeguardian-studio

macOS

# Install Xcode Command Line Tools
xcode-select --install

npm install -g codeguardian-studio

Windows

# Install Visual Studio Build Tools
# Download from: https://visualstudio.microsoft.com/downloads/

npm install -g codeguardian-studio

Docker

FROM node:20-slim

# Install build dependencies
RUN apt-get update && apt-get install -y \
    build-essential \
    python3 \
    && rm -rf /var/lib/apt/lists/*

RUN npm install -g codeguardian-studio

Troubleshooting

Error: gyp ERR! stack Error: not found: make

• Solution: Install build tools (see above for your OS)

Error: Module did not self-register

• Solution: Node.js version mismatch. Rebuild with:

  npm rebuild better-sqlite3
  

ARM64 compatibility:

• ✅ Supported on Apple Silicon (M1/M2/M3)
• ✅ Supported on Ubuntu ARM64
• May require build from source on some platforms
