| Key features | - Reads live database schema to generate coherent test data automatically
- Generates realistic data at scale from hundreds to tens of millions of rows
- Maintains foreign key integrity and constraint satisfaction
- Generates localized data with culturally appropriate names and formats
- Works as CLI, MCP server for AI editors, and CI/CD pipeline step
- Handles complex schemas with composite keys and multi-level dependencies
- Plan preview shows exactly what will be seeded before writing any rows
- Never requires access to production databases
- Generates data with realistic distributions across columns and tables
- Most runs complete in under three minutes
| - Server matrix showing which MCP servers are enabled across all supported AI clients
- Health checks and MCP Doctor to diagnose server connection failures
- Profiles to save and switch between different MCP stacks for different tasks
- Timestamped backups with atomic writes and external change detection
- Contract Guard to alert when servers change their tool definitions or descriptions
- Built-in catalog and support for custom JSON, JSONC and TOML configuration sources
- Context optimizer measuring tool-schema footprint and proximity to client limits
- Security scanning for invisible characters, credential exposure and malicious prompts in tool definitions
- Optional Gateway mode for supported stdio servers with local routing and native credential storage
- Live Activity logging with metadata-only recording and no payload capture

|---|
| What makes it different | - No production data exposure: generates all test data from schema alone, eliminating privacy and compliance risks
- Schema-aware generation creates coherent, relational data without manual seed scripts
- Integrated with AI editors through MCP server for seamless developer workflow
- Realistic data that surfaces real bugs, not random placeholder values
- Works at any scale with consistent data integrity from dozens to tens of millions of rows
| - Works with any existing MCP server you already have configured without requiring migration or special catalog registration
- Detects and alerts when servers change what they tell your model between health checks
- Completely local with no cloud sync, no account, and no upload of configuration or API keys
- Public source code under MIT License so you can audit every request or build from source yourself
- Automatic timestamped backups before every change with the ability to browse and restore earlier versions
