Payment awareness layer for MCP (Model Context Protocol)
Vaaya MCP server — pay-per-call agent superpowers: media & video generation, product demo videos, web search & scraping, deep/market research, GTM & sales enrichment, code sandboxes, browser automation, email, memory. No API keys.
Public adapters and discovery catalog for Triptych OS (Agent OS): agent frameworks, MCP/A2A/x402 protocols, workflows, wallets, SDKs, and examples for execute-first routing, governed handoffs, and receipt-aware agent commerce.
A neutral landscape analysis of AI agent payment protocols (x402, MPP, L402, Google AP2, Visa TAP + ICC, Mastercard Agent Pay, Amex ACE, Google/Shopify UCP, OpenAI ACP, and others). Maintained by Genesis Software Group, Copenhagen. Updated April 2026. CC BY 4.0.
