Copilot Security

About

This tool provides a comprehensive, customizable `.github/copilot-instructions.md` ruleset and a collection of prompts designed to steer GitHub Copilot towards secure coding defaults. It actively prevents the suggestion of common vulnerabilities and risky patterns in Java, Node.js, C#, and Python, while simultaneously teaching developers secure habits. By integrating these configurations, development teams can enhance their application security posture, ensuring Copilot generates safer, more robust code without hindering workflow efficiency.

Key Features

• Customizable security guidance for Copilot completions.
• Language-specific secure patterns for Java, Node.js, C#, and Python.
• "Do Not Suggest" lists to block risky code completions (e.g., `eval`, inline SQL).
• AI hallucination protections to prevent package spoofing and non-existent API suggestions.
• Integrated MCP server for centralized prompt management and deployment.
• 20 GitHub stars

Use Cases

• Conducting secure code audits on specific files using Copilot Chat prompts.
• Preventing the introduction of common vulnerabilities during real-time code generation.
• Centralizing and deploying secure coding prompts across development teams via an MCP server.
