🚀 mixlink is Open Source! Build your own A2A gateway.

Stop parsing HTML. Build for A2A.

Mixlink is an open-source headless commerce gateway. Native Model Context Protocol (MCP), routing via llms.txt, and an autonomous Negotiation Engine. Let AI agents bargain and buy directly through a JSON API.

No “div soup”. A clean negotiation protocol with protection against automated minimum-price probing and built-in stochastic guardrails.

Discovery (llms.txt)

Machine-readable routing. Agents find your products not through SEO, but through standardized chains: robots.txt → llms.txt → agentic_actions.

Negotiation Engine

Forget static prices. The seller sets cost_price; floor_price defaults to cost × 1.2 (optional manual override, never below cost). The engine runs autonomous bargaining with buyer agents, using stochastic guardrails against oracle attacks.

MCP Ready

Model Context Protocol out of the box. Local LLMs and cloud agents connect to your node over SSE, fetch the catalog, and negotiate — no custom HTML parsers.

Spin up your node in 2 minutes.

Need self-host without the cloud? The open-source version is on GitHub.

A2A Protocol Roadmap

Product path for Mixlink as a decentralized commercial Node: autonomous storefront today, bring-your-own-model next, federated A2A commerce ahead.

Zero Density Roadmap

We don’t build castles in the air, and we understand the cold-start problem of P2P networks. Our protocol lifts protective limits only on data-driven network-density metrics. See how we balance defense and an open market in the public document.
