MCPs › Data & APIs › MockHero
MockHero generates realistic, relational synthetic test data from a JSON schema, plain-English prompt, or template — 156 field types, 22 locales, JSON/CSV/SQL output, with valid foreign keys across related tables (orders reference real user IDs, reviews link to real products). Built for AI coding agents and developers who need seed data, fixtures, demo data, or QA datasets without hand-writing repetitive faker scripts. Free keyless preview: generate up to 100 records per request with an explicit table schema, no signup or API key required. For larger volumes or plain-English prompt generation, get an API key by creating a loginless Polar checkout (no account needed) — 500 free records/day, then $0.001 per 100 records billed monthly. Polar is the Merchant of Record. Deterministic seeds make output reproducible across runs. Locale-aware data (names, phone formats, addresses) covers 22 locales.
