modbender Permission Auditor
Your API has 47 routes and no permission system. This tool scans your route handlers and generates RBAC permission configs automatically. It figures out which endpoints need which roles and outputs a config you can plug right into your middleware.
One command. Zero config. Just works.
Quick Start
npx ai-permission src/routes/
What It Does
- Scans route handlers and API endpoints to map out your permission surface
- Generates role-based access control configurations
- Detects admin-only routes, public routes, and auth-required routes
- Outputs middleware-ready permission configs
- Identifies routes missing auth checks
Usage Examples
npx ai-permission src/routes/
npx ai-permission src/api/
npx ai-permission "src/**/*.controller.ts"
Best Practices
- Start with least privilege - Default deny, then explicitly grant access
- Review generated configs - The tool suggests roles but you know your business logic
- Keep permissions close to routes - Don't scatter permission checks across your codebase
When to Use This
- Building a new API and need to plan permissions
- Retrofitting RBAC onto an existing app
- Auditing which routes have missing auth checks

How It Works
Scans your route files to extract endpoint definitions, HTTP methods, and existing auth middleware. AI analyzes the patterns to suggest appropriate role assignments and generates a structured RBAC config.
