In this episode, we dive deep into the OWASP MCP Top 10, the first official security framework dedicated to the Model Context Protocol (MCP).

Get hands-on experience in tool poisoning labs, OAuth 2.1 hardening, MCP red-teaming, and shadow server detection. This is the definitive certification to secure agentic AI in 2026.

This framework addresses a critical shift in the threat model: as agentic AI moves into production, agents no longer rely on a small, hardcoded toolset but instead discover tools at runtime from any reachable server. This transition has turned every MCP server into a high-stakes trust boundary.

We explore the sobering reality of 2026 security, where over 30 CVEs targeting MCP were filed in the first two months of the year alone; with shell injections making up 43% of those attacks. We break down the most critical risks, including:

MCP01 (Token Mismanagement): How attackers exploit hard-coded credentials and long-lived tokens through prompt injection.

MCP03 (Tool Poisoning): The danger of malicious instructions hidden in tool descriptions that the model reads, but the user never sees.

MCP05 (Command Injection): The leading attack pattern in 2026, where agents build dangerous shell commands from untrusted input.

MCP09 (Shadow MCP Servers): The risk of rogue servers impersonating trusted ones to hijack tool calls.

Finally, we discuss a week-by-week prioritization strategy to help security teams close the most dangerous gaps first, starting with token hygiene and OAuth 2.1 implementation. With a massive skills gap currently facing the industry, mastering these categories is no longer optional for AppSec engineers.
