It's a few months since we had a blog about Spring gRPC that wasn't just a release announcement. This one marks the first release since the project was promoted from experimental to a full member of the Spring Portfolio. This doesn't change the way you consume the project, but it has some implications for support and symbolically for what the project now means to the portfolio.

The latest release is 0.8.0, and it has been available for a couple of weeks now in Maven Central.

The Model Context Protocol (MCP) is a powerful feature in Spring AI that enables AI models to access external tools and resources through a standardized interface. One interesting capabilities of MCP is its ability to dynamically update available tools at runtime.

This blog post explores how Spring AI implements dynamic tool updates in MCP, providing flexibility and extensibility to AI-powered applications.
