The MCP spec mandates OAuth 2.0 for HTTP-exposed servers, but most tutorials stop at "add a Bearer token." Enterprise deployments demand more: dynamic client registration, tool-level authorization, token introspection under load, and audit trails for compliance.

This session builds a production-grade MCP server with Spring Boot and the MCP Java SDK, secured by Keycloak. We cover: mapping OAuth scopes to MCP tool permissions, rate limiting per client credential with Bucket4j, wiring OpenTelemetry traces through the MCP request lifecycle, and handling edge cases at scale — token clock skew across distributed agents, graceful degradation when the IdP is unreachable, and preventing prompt injection from leaking privileged tool responses.

Attendees leave with a working architecture adaptable to any identity provider and a clear mental model of where MCP security ends and application security begins.

Breakdown: threat model (3 min), OAuth 2.0 + Keycloak layer (7 min), hardened Spring Boot server (8 min), edge cases from the field (5 min), architecture takeaway (2 min).
