I scanned my MCP setup and it scored 0/100. Here's what was wrong.
Short summary
A survey of 7,000 public MCP servers revealed critical security gaps: 41% require no authentication, 36.7% are SSRF-vulnerable, and only 8.5% use OAuth. mcp-audit, a free open-source CLI, scans your local MCP config (Claude Desktop, Cursor, VS Code) and flags issues like plaintext secrets, unpinned executables, and context bloat. The author provides concrete fixes: move secrets to env vars, pin versions, scope filesystem access, and add auth to remote servers.
