AgentGrade scans websites for AI-agent readiness, checking discovery files, payment protocols, MCP/OpenAPI support, identity signals, and related infrastructure. It returns scored reports, badges, history, and remediation guidance for improving a site's agent accessibility.
AgentGrade exposes a public HTTP API documented by an OpenAPI spec at `https://agentgrade.com/openapi.json` and a public MCP server at `https://agentgrade.com/mcp`; no CLI or GraphQL surface was found, and current docs state the published endpoints are free with no authentication.
