Model Context Protocol — Architecture
Module 12's tools lived inside your own application. What if you want to expose tools as a standalone service other AI applications (not just yours) can use — or consume someone else's tools without writing a custom integration for every one? That's what MCP is for.
Learning objectives
- Beginner: Explain what problem MCP solves that plain in-app tool calling doesn't.
- Intermediate: Build a minimal MCP client that connects to an existing MCP server using Spring AI.
- Advanced: Build and expose your own MCP server, and reason about when STDIO vs. a remote transport is the right choice.
