This is part of the Sovereign MCP collection and gives Claude eyes on code health metrics. It exposes five tools for analyzing cyclomatic complexity, detecting duplicate code blocks, checking naming conventions, identifying refactoring opportunities, and generating quality reports. You'd reach for this during code reviews or when cleaning up legacy codebases. It runs via npx without installation and connects over stdio. The tool set covers the basics: complexity scoring to find gnarly functions, duplication detection to spot copy-paste debt, and naming analysis to enforce consistency. It's deterministic analysis, not AI inference, so you get repeatable metrics you can track over time or gate on in CI.
