Cursor Rules MDC Generator — Auto-Generate from Docs

How It Works

1. You specify a library (e.g., React, FastAPI, Prisma)
2. Exa semantic search finds documentation, best practices, and patterns for that library
3. LLM processes the gathered information into a structured .mdc rule file
4. Output is a ready-to-use Cursor rule file tailored to that specific library

Usage

Generate for a specific library

uv run src/generate_mdc_files.py --library fastapi

Generate for a category

uv run src/generate_mdc_files.py --tag backend

Batch generate with concurrency

uv run src/generate_mdc_files.py --workers 4 --rate-limit 10

Regenerate all rules

uv run src/generate_mdc_files.py --regenerate-all

Adding New Libraries

Edit rules.json:

{
  "name": "your-library",
  "tag": "category"
}

Then run the generator to create the .mdc file automatically.

Requirements

• Python 3.8+
• Exa API key (for semantic search)
• LLM API key (Gemini, OpenAI, or Anthropic)
