Ship the protocols that run the agentic web.
MCP connects agents to your tools. UCP makes your store discoverable to agent platforms. ACP lets agents check out and pay you. saify.dev ships production-grade backends and starters for all three — documented, tested, licensed for client work.
Three rails. One practice.
Agentic Commerce Protocol
How agents check out. Checkout sessions, delegated payments, and order webhooks — so ChatGPT and friends can buy from your store.
OpenAI × StripeUniversal Commerce Protocol
How stores get discovered. A standard surface your storefront publishes so agent platforms can find, read, and transact with it.
GoogleModel Context Protocol
How agents use tools. The open standard that connects models to your data and APIs — the substrate everything else runs on.
AnthropicThe flagship.
AgentCart ACP
