TAR Engine Overview
TAR Engine MCP server audits AI agent skills for static red flags, semantic misuse, adversarial prompt behavior, and supply-chain risks. It accepts supported skill files and returns a 0–100 score, A–F grade, risk class, and findings tied to source lines. The MCP package runs through uvx and uses tarai.dev by default, while semantic and adversarial checks require an explicitly supplied OpenAI key. Reach for it when reviewing skills before publication, enforcing score thresholds in CI, or checking skills during development in Claude Code, Cursor, or Codex CLI.
Primary Use Cases for TAR Engine:
- Audit skills before publishing them
- Gate CI builds on minimum audit scores
