Recently, I explored how the Model Context Protocol (MCP) is gaining traction in the Java ecosystem, with frameworks like Spring AI, Quarkus, and LangChain4j starting to adopt it for integrating language models via standardized interfaces. It was also time to start experimenting with writing an MCP Server myself (well maybe not the first time). Certainly, I don’t want to be left out of all the cool things being demonstrated by the community. The goal for me is to learn, and creating perhaps a more practical example.
In this post I am going to choose Keycloak, and write an experimental MCP server implementation for Keycloak. The post is also to spark interest around this topic: Will it be useful to have an MCP server for Keycloak?
