powerful foundation to create your own Java based servers that can bridge AI with any data source or system you can imagine.

Whether you want to connect to your favorite database, integrate with your company’s internal systems, or build something completely new - the sky

truly is the limit! The simplicity of implementing MCP servers with AJ

means you can focus on the creative aspects rather than the plumbing.
