Why it matters
MCP authorization is a core control for preventing unauthorized access and tool abuse in agentic AI deployments, so defenders building or hardening MCP servers need to understand these OAuth flows.
Official Model Context Protocol documentation explains how authorization works for MCP servers, describing standardized OAuth 2.1-based flows, Protected Resource Metadata discovery, and 401/WWW-Authenticate handshakes used to secure access to sensitive resources and operations exposed by MCP servers. The tutorial covers when authorization is recommended and how local (STDIO) versus remote (HTTP) transports differ in credential handling.
