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.

$3

| 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:

``bash


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.
