20. @edeandrea Model Context Protocol (MCP) Instead of exposing tools from your code, discover and use remote services https://modelcontextprotocol.io

24. @edeandrea @edeandrea Lessons Being Learned
25. @edeandrea • The model matters • Tell the model what’s going on • Keep LLM arguments concise • Don't use JPA entities as tool arguments • Be (overly) descriptive • MCP is like the wild west • Testing is hard • Faster time to market without AI? Lessons learned (or in process of learning)
