ucp-commerce-validator
x402-mcp-validator
  • a2a-agent-validator: A2A Protocol agent card discovery and AP2 extension detection
  • x402-mcp-validator: x402 payment protocol validation — probes all four schemes (exact, upto, batch-settlement, auth-capture) and MCP connection/version-branch capabilities
  • erc8004-registry-parser: ERC-8004 on-chain agent registry parsing and validation
  • mcp-apps-validator: MCP Apps UI resource detection and validation
  • ucp-commerce-validator: UCP (Universal Commerce Protocol, Google/Shopify) and ACP (Agentic Commerce Protocol, OpenAI/Stripe) validation — fetches .well-known/ucp and ACP feed/discovery, validates manifest structure, classifies commerce capabilities, and flags the MCP transport

Experimental

Title Updated Release Workflow Coverage Issues License
ucp-prava-grader
  • ucp-prava-grader (hackathon experiment): "Payable" — a probabilistic categorization layer on top of the UCP-Commerce validator that maps each merchant to an MCC and grades it against Prava §8 (payable-via-Prava: eligible / prohibited / not_assessed). A standalone experiment, not pinned into the assessment engine.
