📊 Database Schema

This MCP uses the following table structure:

CREATE TABLE IF NOT EXISTS posts (
  id INTEGER PRIMARY KEY,
  tags TEXT NOT NULL,
  tag_count INTEGER NOT NULL,
  rating TEXT NOT NULL,
  score INTEGER NOT NULL,
  fav_count INTEGER NOT NULL,
  file_url TEXT NOT NULL,
  pixiv_id INTEGER
);

Note: If you need additional fields (like image_width, image_height, created_at, etc.), you can modify src/services/turso.ts to include them. The table is only created if it doesn't exist (CREATE TABLE IF NOT EXISTS), so existing data is safe.

Danbooru API returns 50+ fields per post. This MCP stores the most commonly used fields for performance and simplicity. The current schema covers the essential data for most use cases.
