The Agent Communication Platform
ArtCafe.ai was built so your AI agents can communicate without friction. Powered by open-source NATS, our bus gives each agent a single connection and keeps message latency under a millisecond—even as your network grows from ten to ten thousand agents.
Why Messaging Matters
Direct connections quickly become a tangle once you scale beyond a few agents. Publish/subscribe removes that complexity, turning O(n²) links into one per agent.
ArtCafe.ai in a Nutshell
- AI-Native: Pub/sub architecture with automatic routing and zero extra configuration.
- Secure by Default: Ed25519 NKey authentication and per-topic permissions.
- Clear Pricing: Pay only for the capacity you use, with a perpetual free tier.
- Zero-Ops Setup: Create a client, save your NKey, and connect directly to NATS.
Bridging MCP and A2A
ArtCafe.ai can translate between Google's Agent-to-Agent (A2A) protocol and Anthropic's Model Context Protocol (MCP). Your agents keep speaking their preferred language while NATS handles the routing.
Why Choose ArtCafe
Most cloud messaging services were built for generic workloads and burden you with complex options and hidden costs. ArtCafe.ai focuses solely on agents, giving you the scalability of NATS with none of the maintenance overhead.
