AgentGrade

This is a diagnostic tool for the emerging ecosystem of AI-accessible web services. It scans URLs for agent-specific protocols like x402, MPP, L402, and discovery endpoints, then returns Lighthouse-style reports grading a site's readiness for programmatic access by AI agents. You get four tools: a full scan with comprehensive protocol detection, a compact version returning just capabilities and a numeric score, history lookups if you've configured a database, and a standalone x402.json validator. Reach for this when you're building agent workflows and need to quickly assess whether a target site exposes machine-readable payment rails, service definitions, or structured discovery metadata before attempting integration.
