Integrating LLMs in Java A Practical Guide to Model Context Protocol
summary
Claims that the Model Context Protocol standardizes how LLMs access tools and data and that a Java SDK (donated by Spring) makes enterprise MCP servers practical. Shows a working Spring-based MCP server exposing a getRecentVideos tool that returns the last five YouTube videos, validated with the MCP Inspector and used from ChatGPT/Claude clients. Covers transports (stdio vs streamable HTTP), OAuth2 security, token/context-window costs and the tradeoff of many tools eating context and cost.
