Documentation Search MCP Server

# 🛡️ Security Enhancement Proposal for Documentation Search Enhanced MCP Server ## Executive Summary Your MCP server already has excellent security foundations with vulnerability scanning, security scoring, and dependency analysis. This proposal outlines strategic security enhancements to make it enterprise-grade, including integration with commercial security tools like Snyk, additional SAST/DAST capabilities, and comprehensive security automation. ## Current Security Posture Analysis ### ✅ Existing Security Features (Excellent Foundation) - **Vulnerability Scanner**: Multi-source scanning (OSV, GitHub Advisories, Safety DB) - **Security Scoring**: 0-100 scale risk assessment - **Project Dependency Analysis**: Scans pyproject.toml, requirements.txt, package.json - **Security Comparisons**: Side-by-side library security analysis - **Auto-approval Controls**: Configurable approval for sensitive operations - **Input Validation**: Configuration validation with Pydantic - **API Key Protection**: Environment variable management ### 🎯 Security Enhancement Opportunities --- ##
