Paarroo MCP

Serveur MCP (Model Context Protocol) qui expose un ensemble de règles et d'outils d'analyse pour standardiser la qualité du code Rust, CSS, WASM et l'architecture hexagonale.

Principe

Au lieu de répéter les mêmes bonnes pratiques dans chaque projet — gestion d'erreurs, performance, sécurité, architecture — ce serveur centralise tout dans des ressources rule:// et des outils d'analyse. L'IA les applique automatiquement sur n'importe quel projet.

Outils d'analyse

• Analyse Rust — code mort, sécurité (hardcoded secrets, crypto RNG, dotenv prod, secrets logging), dépendances (cargo-deny, cargo-outdated, cargo-audit), call graph
• Analyse CSS/SCSS — score qualité (0-100), oklch conversion, contraste WCAG, stylelint subprocess
• Analyse WASM — validation wasm-tools, wasm-pack build, binaryen wasm-opt
• Analyse architecture — hexagonal layering, dépendances, seuils de fichiers/fonctions
