11 CLI Commands
Run, validate, preview, init, inspect schemas, manage connectors, and more. JSON output mode for scripting and automation pipelines.
AI-Native MCP Server
10 tools for Claude, Cursor, and other AI agents via the Model Context Protocol. Let AI inspect, generate, validate, and run migrations.
Web Dashboard
Real-time progress monitoring with a React UI. Track migration status, view logs, and manage projects through your browser.
