About Nacos
Nacos is turning a microservice registry into a registry for AI agents.
Nacos maintains three lines at once: 2.x on a JDK 8 baseline for legacy deployments, 3.2.x as the current stable series, and a 3.3.0 beta carrying the new work. The 3.x line has absorbed an AI Registry that now covers MCP servers, Skills, Prompts and Agents, with a rebuilt console to manage them. The 3.3.0 beta adds protocol-neutral agent registration with endpoint discovery and Java SDKs, hybrid keyword-plus-vector discovery for AI resources, and a first phase of distributed locks.
