Learn how to implement robust security for Model Context Protocol (MCP) servers using Spring AI and Spring Security in this comprehensive 23-minute tutorial. Discover essential authentication strategies including OAuth2 and API key implementations to protect your MCP servers when transitioning from local development to production environments. Master OAuth2 authentication with Spring Authorization Server and GitHub as an identity provider, while understanding federated authentication flows through practical analogies. Explore API key authentication setup for simpler security layers and learn to test secured MCP servers using the MCP Inspector tool. Follow along with real-world code demonstrations covering security configuration with Spring Security, live testing of both authentication methods, and production deployment considerations. Gain insights into choosing the appropriate authentication approach based on your specific requirements, whether you need enterprise-grade OAuth2 security with user identity management or simpler API key protection for quick deployments. Address critical security vulnerabilities being discovered in unsecured MCP servers and implement practical solutions to protect your production deployments with working examples and best practices for secure MCP server development.
