MCP Server Security Auditor

78.3% attack success rate once 5 servers are connected.

Palo Alto Unit 42 measured a 78.3% attack success rate once five MCP servers were connected to an agent, and a 2026 review found 43% of audited MCP servers contained command injection bugs, with over 30 CVEs filed against MCP servers in a two-month period. CISA and NSA have flagged core gaps: no OAuth enforcement, tools returning more data than needed, and missing audit trails. This tool actually parses a pasted MCP manifest/config and checks for exactly these documented gap patterns — missing authentication, wildcard tool scopes, arbitrary shell execution tools, and hardcoded secrets.
