This is a pre-deployment quality gate for AI agents and MCP servers. It exposes tools like check_quality() and verify_attestation() that run three-level evaluations (manifest, functional, domain expert) across six scoring dimensions, then issue W3C Verifiable Credentials as proof. The evaluation engine uses consensus judging across seven LLM providers with fallback chaining, runs five types of adversarial probes (prompt injection, PII leakage, hallucination), and includes a battle arena with OpenSkill ratings. Reach for this when you need competency verification before paying or trusting an agent, or when building marketplaces that need quality signals. It speaks Google A2A v0.3 natively and integrates with x402 payment verification on Solana.
