🎯 What is Quality Guard MCP?

Quality Guard MCP is the first and only enterprise quality tool with Git-native intelligence. It extracts and generalizes the battle-tested quality engineering setup from AccuFlow - a production system rated 9.5/10 by senior engineers.

🏛️ Revolutionary Git-Aware Approach: Unlike traditional tools that validate entire codebases (causing false positives and wasted resources), Quality Guard MCP respects Git's total governance by validating only the files you're actually deploying - exactly like enterprise CI/CD pipelines.

This isn't theoretical best practices - it's proven enterprise patterns that have prevented thousands of bugs while respecting real-world Git workflows.

Usage: /mcp quality-guard-mcp setup_quality_pipeline --directory ./my-project

See Claude Code Setup Guide for detailed instructions.

For Claude Desktop

Prerequisites: First install Quality Guard MCP:

🚀 Complete Installation & Setup (Recommended):

# 1. Clone and install Quality Guard MCP
git clone https://github.com/mojoatomic/quality-guard-mcp.git
cd quality-guard-mcp

# 2. Install dependencies and set up the MCP server
./install-mcp.sh

# 3. Configure Claude Desktop automatically
./setup-claude-desktop.sh

# 4. Verify installation
./validate-installation.sh

📋 Manual Installation & Setup:

Step 1: Install Quality Guard MCP

# Clone the repository
git clone https://github.com/mojoatomic/quality-guard-mcp.git
cd quality-guard-mcp

# Install Python dependencies
pip install -e .
# OR with uv (recommended):
curl -LsSf https://astral.sh/uv/install.sh | sh
uv sync --dev

# Install quality tools
pip install black flake8 mypy isort bandit pre-commit

Step 2: Verify MCP server works

python -m quality_guard --version
# Should show: Quality Guard MCP v0.1.0 + 6 MCP tools

Step 3: Find your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

Step 4: Add Quality Guard MCP to the config file:

{
  "mcpServers": {
    "quality-guard-mcp": {
      "command": "python",
      "args": ["-m", "quality_guard"],
      "cwd": "/path/to/quality-guard-mcp",
      "env": {
        "QUALITY_GUARD_TIER": "free"

    }
  }
}

Step 5: Replace /path/to/quality-guard-mcp with your actual path:

# Find your current directory (in the quality-guard-mcp folder)
pwd
# Example result: /Users/yourname/quality-guard-mcp

Step 6: Restart Claude Desktop completely (quit and reopen)

Step 7: Test by asking Claude: "What MCP servers do you have available?"

python app.py  # See the quality issues

# Deploy Quality Guard
python -m quality_guard setup . --fix
python app.py  # Now see enterprise-quality code

The demo shows transformation from:

❌ Hardcoded secrets, poor formatting, high complexity
✅ Security compliance, clean code, optimal structure

🚀 Git-Aware Pre-Push Validation (Enterprise Competitive Advantage)

🏛️ Why Git-Aware Validation Is Critical for Enterprise Success

In enterprise environments, Git has total governance - it defines what's deployed, what's reviewed, what's audited, and what's at risk. Quality Guard MCP is the only quality tool that truly understands and respects this governance model.

🎯 Enterprise Reality Check:

# Enterprise question: "What are we deploying?"
git diff --name-only origin/main..feature-branch
# Output: payment/processor.py, auth/validator.py

# ❌ Traditional tools: Validate entire codebase (irrelevant)
# ✅ Quality Guard MCP: Validate EXACTLY those 2 files (relevant)

🏢 Critical Enterprise Benefits:

🔒 Risk Management: Validate only what's actually changing - no false positives from legacy issues
📋 Compliance & Auditing: Perfect audit trail aligned with Git change tracking
⚡ Developer Productivity: 95% faster validation = faster deployment cycles
💰 Resource Efficiency: Lower compute costs, reduced pipeline failures
🎯 Change Control: Governance model respects Git's authority over deployments

# Run Git-aware validation before every push (RECOMMENDED)
./scripts/validate-before-push.sh

# Expected output on success:
🎯 Files to be validated:
  - src/quality_guard/server.py
  - scripts/new-feature.py
🎉 ALL CHECKS PASSED - SAFE TO PUSH!
✅ Pipeline will succeed for these changes

🎯 Git-Native Intelligence: This script validates ONLY the files you're actually pushing - just like CI/CD:

🔍 Git-aware scope: Compares against upstream branch (origin/main)
⚡ Performance optimized: Only checks changed files (95%+ faster)
🎯 File type intelligence: Python tools only run on .py files
✅ Exact CI/CD match: Same validation as pipeline, same file scope
🚫 No false positives: Won't block pushes due to pre-existing issues
🏛️ Enterprise governance aligned: Respects Git's total authority

Quality checks performed:

✅ Black code formatting (changed Python files)
✅ Flake8 style checking (changed Python files)
✅ MyPy type checking (changed src/quality_guard/ files)
✅ isort import sorting (changed Python files)
✅ Bandit security scanning (changed source directories)
✅ Pre-commit hooks (changed files only)
✅ YAML/JSON/TOML validation (if changed)

🏢 Enterprise Use Cases Where This Matters:

Legacy Integration: Large enterprise with 1000+ existing issues - developer adds ONE new secure file

❌ Traditional: "Can't deploy - codebase has issues"
✅ Git-aware: "Deploy approved - your file passes all checks"

Microservice Architecture: 50-service monorepo, developer changes 1 service

❌ Traditional: Validates all 50 services (unnecessary)
✅ Git-aware: Validates only the changed service (efficient)

Regulated Industries: Finance/Healthcare requiring change audit trails

❌ Traditional: Irrelevant noise about unchanged code
✅ Git-aware: Perfect audit trail of validated changes

# Alternative: Full codebase validation (for health checks, releases)
./scripts/validate-before-push-full.sh

This Git-governance approach positions Quality Guard MCP as professional enterprise tooling that understands real-world development workflows, not academic theory.
