Atelier
MCP quality gate for AI-generated code
AI coding agents optimise for less code, not correct code. Atelier adds the verification layer: two specialist critics — a UI/UX Quality Gate and a Backend Architecture Guard — run post-generation over an MCP server and return structured pass/fail verdicts with rule ID, severity, line and fix. atelier fix applies the remediation directly.
- 36
- Mechanically gradeable rules
- ~12ms
- Deterministic pass, zero API cost
- 5
- Editors from one ruleset
- Local
- Qwen LoRA critic via Apple MLX
- Rules checked by AST parsing, regex and JSON-schema validation — not vibes
- Fine-tuned Qwen2.5-Coder QLoRA critic distilled from a frontier teacher model
- Model fallback only for judgment calls the deterministic pass can't settle
- Native MCP server plus adapters: Cursor, Windsurf, Claude Code, Antigravity, Copilot
