Demonstrates how to secure Model Context Protocol (MCP) servers and clients using Spring AI and OAuth2. The tutorial builds a complete system with three components: an OAuth2 authorization server for issuing JWT tokens, a protected MCP server with calculator tools that validates tokens, and a client that handles both user and system authentication flows. The implementation uses Spring Security's OAuth2 support to separate security concerns from business logic, with the MCP server acting as an OAuth2 Resource Server that validates JWT tokens before processing operations.
