@vooster/c2c - Cursor to Claude Converter

Convert Cursor IDE rules (.mdc files) to Claude AI markdown format with intelligent metadata parsing and categorization.

Installation

npx @vooster/c2c

Usage

Run the command in any directory containing .cursor folders:

npx @vooster/c2c

The tool will:

1. Recursively find all .cursor directories
2. Locate all *.mdc files within them (including nested subdirectories)
3. Parse metadata (alwaysApply, description, globs) from files
4. Convert them to markdown files in a c2c-rules directory (with metadata stripped)
5. Generate an advanced _root.md index file with categorized references:
   • Rules that always apply
   • Rules that apply based on description matching
   • Rules that apply based on glob pattern matching

Example

Given this structure with metadata:

project/
├── frontend/
│   └── .cursor/
│       ├── rules.mdc (with alwaysApply: true)
│       └── components/
│           └── ui-rules.mdc (with globs: "**/*.vue")
└── backend/
    └── .cursor/
        └── api/
            └── guidelines.mdc (with description: "API guidelines")

Running npx @vooster/c2c will create:

c2c-rules/
├── _root.md
├── frontend/
│   ├── rules.md
│   └── components/
│       └── ui-rules.md
└── backend/
    └── api/
        └── guidelines.md

The _root.md will contain:

# Cursor Rules Collection

always apply below rules
- rules: @frontend/rules.md

apply below rules if requirement matches
- guidelines
    - description: API guidelines
    - path: @backend/api/guidelines.md

apply below rules if glob pattern matches with related files:
- ui-rules
    - glob: **/*.vue
    - path: @frontend/components/ui-rules.md
