About MockHero
MockHero is an MCP server published by the GitHub account dinosaur24. Generate realistic relational test data — 156 field types, 22 locales, JSON/CSV/SQL, free previews.
It runs on your own machine: your AI client starts it from the npm package @mockherodev/mcp-server at version 0.2.0, or you can connect to the hosted version instead.
It asks for one secret: MOCKHERO_API_KEY. Give it a key with the least access that still works.
Version 0.2.0 was published on 3 July 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 10 automated checks on the registry entry and the package code: 8 pass, 0 warn, 0 fail, 2 info. How we check.
