Finding what to refactor first, tracking technical debt, and maintaining context across long coding sessions can be overwhelming.</p> <p>I built Code Guardian Studio to solve these problems using the Model Context Protocol (MCP).</p> <h2> What is Code Guardian Studio? </h2> <p>It's an MCP server that provides 80+ tools for:</p> <h3> 1. Code Analysis </h3> <ul> <li>Scan repositories for complexity metrics</li> <li>Detect "hotspots" - files that need attention</li> <li>Calculate Technical Debt Index (TDI)</li> </ul> <h3> 2. Persistent Memory </h3> <ul> <li>Remember decisions across sessions</li> <li>Store code patterns and conventions</li> <li>Recall similar errors and their fixes</li> </ul> <h3> 3. Code Guards </h3> <ul> <li>Validate code before commits</li> <li>Catch fake tests, empty catch blocks</li> <li>Security-focused rules</li> </ul> <h3> 4. Workflow Management </h3> <ul> <li>Task tracking with priorities</li> <li>Checkpoint system for progress</li> <li>Process management for dev servers</li> </ul> <h2> Quick Start </h2> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code><span class="c"># Install</span> npm <span class="nb">install</span> <span class="nt">-g</span> codeguardian-studio <span class="c"># Add to Claude Code settings</span> ccg init </code></pre> </div> <h2> Example: Finding Refactoring Priorities </h2> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>Claude: Use code_quick_analysis to scan the codebase Result: - Top hotspot: src/legacy/parser.ts (score: 8.5) - 500+ lines, deep nesting, high complexity - Suggested: Split into smaller modules </code></pre> </div> <h2> Links </h2> <ul> <li>GitHub: <a href="https://github.com/phuongrealmax/claude-code-guardian" rel="noopener noreferrer">https://github.com/phuongrealmax/claude-code-guardian</a> </li> <li>Website: <a href="https://codeguardian.studio" rel="noopener noreferrer">https://codeguardian.studio</a> </li> <li>npm: codeguardian-studio</li> </ul> <p>What features would you find most useful for your workflow?
