## Intro

Awesome Cursor Rules MDC is a collection of 800+ auto-generated `.mdc` (Markdown Cursor) rule files for Cursor AI editor, with 3,400+ GitHub stars and CC0 (public domain) license. Unlike hand-written `.cursorrules` files, these are generated using Exa semantic search to gather real-world best practices, then LLM (Gemini/OpenAI/Anthropic) to create structured coding guidelines. Drop any `.mdc` file into your project's `.cursor/rules/` directory and Cursor immediately follows your framework's conventions — React patterns, Python style, Rust idioms, and more.

Best for: Cursor users who want instant, high-quality coding rules for any library without writing them manually.
Works with: Cursor 2.2+ (`.mdc` format), any framework/library.
Setup time: under 1 minute.

## How .mdc Rules Work

### What's in a .mdc File

Each `.mdc` file contains structured coding guidelines:
- Framework-specific best practices
- Naming conventions and patterns
- Common anti-patterns to avoid
- Import/export standards
- Testing conventions
- Performance recommendations

### .mdc vs .cursorrules

| Feature | .cursorrules (legacy) | .mdc (current) |
|---------|----------------------|----------------|
| Format | Plain text | Structured markdown |
| Scoping | Project-wide only | Glob-scoped per file type |
| Metadata | None | Frontmatter with description |
| Organization | Single file | Multiple files in `.cursor/rules/` |
| Future | Being deprecated | Recommended format |

### Generation Pipeline

1. **Exa Semantic Search** — Finds real-world best practices, official docs, community patterns
2. **LLM Processing** — Structures findings into .mdc format (supports Gemini, OpenAI, Anthropic)
3. **Parallel Processing** — Generates multiple libraries simultaneously
4. **Smart Retry** — Failed generations auto-retry on next run

### Custom Generation

Generate rules for any library:
```bash
uv run src/generate_mdc_files.py --library "next.js"
uv run src/generate_mdc_files.py --tag "python"
uv run src/generate_mdc_files.py --regenerate-all
```
