Snyk MCP-Scan
MCP-Scan is an open-source tool for analyzing Model Context Protocol (MCP) setups. It automatically discovers and secures MCP servers (e.g Claude, Cursor, Windsurf), Agent Skills, and Data pipelines and scans them for common security issues such as prompt injection, tool poisoning, toxic flows, and other vulnerabilities.
Start with these commands:
npx snyk@latest mcp-scan --experimentalScans your installed servers for security vulnerabilities in tools, prompts, and resources (automatically discovers MCP configs, including Claude, Cursor, Windsurf, etc.). Identify Toxic Skills via SKILL.md files containing obfuscated malware, backdoors, and prompt injection payloads.
mcp-scan ~/.vscode/mcp.jsonScans a particular MCP server configuration. For example, a VS Code MCP config.
