The Model Context Protocol (MCP), introduced by Anthropic in late 2024, has rapidly attracted security research attention since early 2025. As MCP adoption grew through clients like Cursor and Claude Desktop, researchers discovered that many MCP servers contain serious vulnerabilities including command injection, path traversal, and SSRF. Security concerns extend beyond identity and access management to supply chain attacks and tool poisoning. The author, who has personally researched and found dozens of insecure MCP servers, draws parallels to common Node.js security issues covered in their secure coding books.
