Java MCP Servers

MCP servers built with Java and JVM languages (Java, Kotlin, Quarkus, Spring Boot) that provide protocol implementations, SDKs, and server examples. Does NOT include general MCP clients, non-JVM language implementations, or MCP servers that merely happen to be written in Java without focusing on the protocol/SDK aspect.
