Claude Code Guardian

CCG stands out as themost comprehensive MCP serverfor Claude Code:

- All-in-one: Guard + Metrics + Workflow + Memory in a single server
- 113+ MCP tools: The most comprehensive toolset available
- Session management: Resume work across conversations
- Real-time progress: Track refactoring progress with live dashboard
- Latent Chain: Multi-phase reasoning for complex tasks

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)

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).

- code_scan_repository- Map your entire codebase
- code_metrics- Calculate complexity, nesting, branch scores
- code_hotspots- Find files that need attention
- code_refactor_plan- Generate step-by-step refactor plans
- code_record_optimization- Log optimization sessions
- code_generate_report- Create Markdown reports
- code_quick_analysis- Scan + metrics + hotspots in one call
- code_optimizer_status- Check module status

- Memory- Persistent storage across sessions
- Guard- Block dangerous patterns (fake tests, empty catches, etc.)
- Workflow- Task management and tracking
- Latent Chain- Multi-phase reasoning for complex tasks
- Agents- Specialized agent coordination
- Thinking- Structured reasoning models
- Documents- Documentation management
- Testing- Test runner integration

Dev tier is 100% local and self-hostable. Team/Enterprise require license validation viaapi.codeguardian.studio.

# 1. Install npm install -g codeguardian-studio # 2. Initialize CCG in your project ccg init # 3. Run analysis with custom options ccg code-optimize --report # 4. For advanced options ccg code-optimize --help-advanced

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

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

# Install Xcode Command Line Tools xcode-select --install npm install -g codeguardian-studio

# Install Visual Studio Build Tools # Download from: https://visualstudio.microsoft.com/downloads/ npm install -g codeguardian-studio

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

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

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

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

npm rebuild better-sqlite3

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

This is a web browser that enables your coding agent, such as Claude Code, to visit websites on your behalf and assist you in identifying bugs or creating UI test cases.

A powerful Model Context Protocol (MCP) server that supercharges your Python development workflow with AI-powered code review, intelligent test generation, and comprehensive test execution.

Help agents automatically write and test stories for your UI components

AI-to-AI code review platform — Claude, Codex, and Gemini cross-check each other via MCP, REST API, and CLI for consensus-based results.

A stateful LSP runtime for AI agents: warm language server sessions with 50+ tools for go-to-definition, find-references, diagnostics, rename, and more across 30+ languages.

Persistent code index using Tree-sitter for fast, precise code search. Replaces grep with ~50 token responses instead of 2000+.

Orchestrates a dual-AI engineering loop where a Primary AI plans and implements, while a Review AI validates and reviews, with continuous feedback for optimal code quality. Supports custom AI pairing (Claude, Codex, Gemini, etc.)

AmazingMCP — MCP Server for .NET / C# Codebases

An MCP server that gives AI agents deep understanding of C# codebases via Roslyn — type search, dependency graphs, usage analysis, and architecture overviews, all from a live in-memory compilation.

MCP server that bridges LCOV coverage reports to AI agents.

Uses TypeScript AST to determine which tests are affected by code changes
