Why it matters
MCP is the emerging standard for connecting AI agents to external tools and APIs, and this reference material helps defenders understand and mitigate authorization and confused-deputy risks in agentic deployments.
The official Model Context Protocol (MCP) security best practices document describes attack vectors and mitigations specific to MCP implementations, including the confused deputy problem affecting MCP proxy servers that use static client IDs with third-party OAuth authorization servers. Aimed at developers, server operators, and security professionals, it complements the MCP Authorization specification and OAuth 2.0 security guidance.
