Pluggedin Random Number Generator

# Security Policy ## Supported Versions We actively support the following versions of the Plugged.in Random Number Generator MCP Server: | Version | Supported | | ------- | ------------------ | | 1.0.x | :white_check_mark: | ## Security Features This MCP server implements several security measures to ensure safe and secure random number generation: ### Cryptographically Secure Random Number Generation - **CSPRNG Implementation**: All random number generation uses Node.js built-in `crypto` module functions (`randomBytes`, `randomInt`, `randomUUID`) - **Entropy Sources**: Leverages operating system entropy sources for seed material - **No Predictable Patterns**: Generated numbers are cryptographically secure and suitable for security-sensitive applications ### Input Validation and Sanitization - **Parameter Validation**: All input parameters are validated against expected types and ranges - **Range Checking**: Numeric inputs are checked against minimum and maximum allowed values - **Array Validation**: Choice arrays are validated for proper structure and content - **Type Safety**: TypeScript provides compile-time type checking for additional safety ### Resource Protection - **Rate Limiting**: Built-in limits on generation counts prevent resource exhaustion attacks - **Memory Management**: Efficient buffer handling prevents memory-based attacks - **Error Handling**: Secure error messages that don't leak sensitive system information ### Protocol Security - **MCP Compliance**: Full adherence to Model Context Protocol security guidelines - **JSON-RPC Security**: Proper handling of JSON-RPC requests and responses - **Input Sanitization**: All inputs are sanitized before processing ## Reporting a Vulnerability We take security vulnerabilities seriously. If you discover a security vulnerability in this project, please report it responsibly: ### How to Report 1. **Do NOT** create a public GitHub issue for security vulnerabilities 2. Send an email to: security@plugged.in (if available) or create a private security advisory on GitHub 3. Include the following information: - Description of the vulnerability - Steps to reproduce the issue - Potential impact assessment - Suggested fix (if available) ### What to Expect - **Acknowledgment**: We will acknowledge receipt of your vulnerability report within 48 hours - **Assessment**: We will assess the vulnerability and determine its severity within 5 business days - **Updates**: We will provide regular updates on our progress toward a fix - **Resolution**: We aim to resolve critical vulnerabilities within 30 days - **Credit**: We will credit you in our security advisory (unless you prefer to remain anonymous) ### Vulnerability Severity Levels We classify vulnerabilities using the following severity levels: - **Critical**: Vulnerabilities that could lead to complete system compromise - **High**: Vulnerabilities that could lead to significant data exposure or system access - **Medium**: Vulnerabilities with limited impact or requiring specific conditions - **Low**: Minor vulnerabilities with minimal security impact ## Security Best Practices for Users When using this MCP server, follow these security best practices: ### Deployment Security - **Network Security**: Deploy the server in a secure network environment - **Access Control**: Limit access to the server to authorized clients only - **Monitoring**: Monitor server logs for unusual activity or errors - **Updates**: Keep the server updated to the latest version ### Integration Security - **Client Validation**: Validate that MCP clients are authorized and trusted - **Request Monitoring**: Monitor requests for unusual patterns or excessive usage - **Error Handling**: Implement proper error handling in client applications - **Logging**: Log security-relevant events for audit purposes ### Operational Security - **Regular Updates**: Keep Node.js and dependencies updated to latest secure versions - **Security Scanning**: Regularly scan for known vulnerabilities using tools like `npm audit` - **Backup and Recovery**: Implement proper backup and recovery procedures - **Incident Response**: Have an incident response plan for security events ## Security Considerations for Random Number Usage ### Appropriate Use Cases This server is suitable for: - Cryptographic key generation - Session token creation - Password generation - Security-sensitive random data - Gaming and simulation applications - Statistical sampling ### Inappropriate Use Cases Do not use this server for: - Deterministic testing (use seeded PRNGs instead) - Applications requiring specific statistical distributions beyond uniform - High-frequency trading where microsecond timing matters - Applications requiring hardware-based true random number generators ### Entropy Considerations - The server relies on operating system entropy sources - In virtualized environments, ensure adequate entropy is available - For high-volume applications, monitor entropy pool status - Consider using hardware random number generators for maximum security ## Compliance and Standards This server follows industry security standards and best practices: - **NIST Guidelines**: Follows NIST SP 800-90A recommendations for random number generation - **OWASP**: Implements OWASP secure coding practices - **Node.js Security**: Follows Node.js security best practices - **MCP Protocol**: Adheres to Model Context Protocol security specifications ## Security Audit History | Date | Type | Scope | Result | |------|------|-------|--------| | 2025-07-02 | Internal | Initial security review | No critical issues found | ## Contact Information For security-related questions or concerns: - Security Email: security@plugged.in (if available) - GitHub Security Advisories: Use GitHub's private vulnerability reporting - General Support: Open a public issue for non-security questions --- **Last Updated**: July 2, 2025 **Version**: 1.0.0
