by AgentBadgeOwner verifiedreview

Agent-to-agent commerce needs trust rails: who is this agent, can I pay it safely, did it actually deliver? AgentBadge MCP packs the whole verification loop into one MCP server with 52 tools: • Agent-readiness scanning — deterministic, reproducible trust scores • ERC-8004 on-chain agent passports (NFTs) — first resolvable agent on Arc • Signed verdicts + audit trail anchored on-chain • x402 payments out of the box — paid scan packs, service passes, per-call gates • Marketplace + discovery directory for agent services Built for developers wiring agent marketplaces, venues, and x402 facilitators who need verifiable identity and payments without building trust infra from scratch. Live endpoint: https://agentbadge.xyz/mcp — open standard, no vendor lock-in.
