Report Abuse

Basic Information

This repository provides a curated set of security rules designed to be integrated into Cursor, an AI-assisted development environment. The rules act as guardrails to reduce the risk of unsafe code generation by the Cursor agent, helping teams avoid exposing secrets, executing dangerous system commands, or adopting insecure coding patterns. Users can add the rules to a .cursor/rules directory or the project root to apply them instantly. The collection focuses on enforcing secure development principles, safe Multi-Component Program (MCP) usage, Python security practices, preventing secret leakage in front-end code, and blocking unsafe system operations. The authors are security researchers and the repo is intended for developers and security teams who use Cursor and want automated, shareable constraints that steer AI-assisted code generation toward safer outcomes.

App Details

Features
A compact, opinionated rule set that can be dropped into a Cursor rules directory for immediate effect. Example rule topics include secure development principles, secure MCP usage, Python security best practices, prohibiting secrets in frontend artifacts, and blocking unsafe system commands. The rules are designed to automatically detect and prevent risky patterns produced by Cursor, enforce best practices, and control sensitive operations. Installation is intentionally simple: place rule files under .cursor/rules or the project root. The repository also encourages community contribution and iteration from security researchers and developers to expand and refine the rule coverage.
Use Cases
The rules reduce accidental exposure of credentials and risky behaviors from AI-generated code by providing deterministic checks and constraints applied by Cursor. They help teams control sensitive operations and stop the insertion of unsafe system commands, which lowers operational and security risk in AI-assisted development. By enforcing Python-specific and general secure development guidelines, the rules raise the overall security posture of code produced with Cursor. The easy drop-in installation makes it practical to adopt across projects and to foster a security-first culture, and the project invites contributions from researchers and practitioners to evolve rule coverage over time.
