Mockhero

Mockhero is an MCP (Model Context Protocol) server that enables AI agents, developers, and testers to generate highly realistic, relational synthetic test data for any database schema. It supports over 150 field types, auto-localized data for 22+ countries, and outputs in JSON, CSV, or SQL formats tailored for major databases (Postgres, MySQL, SQLite). Users can define schemas via structured inputs, plain English prompts, or use pre-built templates for instant data generation. Mockhero integrates natively with MCP-compatible AI assistants like Claude, Cursor, and Windsurf, streamlining test data generation and seeding workflows for software teams.
