The OWASP MCP Top 10: A Security Framework for the AI Agent Era

The Model Context Protocol needed its own threat taxonomy. Now it has one. OWASP -- the organization behind the Web Application Top 10 that shaped a generation of security engineering -- has published the MCP Top 10 , a structured framework for the most critical security risks in AI agent tool integration. The project, led by Vandana Verma Sehgal, is currently in beta under a CC BY-NC-SA 4.0 license, and it addresses a gap that has been widening for months: the absence of a shared vocabulary for reasoning about MCP security. This is not a theoretical exercise. Over 30 CVEs have been filed against MCP implementations in the past 60 days. Research consistently shows that tool poisoning attacks succeed at alarming rates -- 84.2% with auto-approval enabled, according to recent benchmarks. An audit of 17 popular MCP servers found an average security score of 34 out of 100, with 100% lacking permission declarations. The threat landscape has outpaced the defensive toolkit, and OWASP’s framewo
