Mockhero
Generate realistic relational fixture data in JSON, CSV, or SQL from your agent when seeding databases or integration tests.
Overview
MockHero is an MCP server for the Ship phase that generates realistic relational test data with 156 field types and 22 locales in JSON, CSV, or SQL.
What is this MCP server?
- 156 field types for relational, realistic test records
- 22 locales for localized sample data
- Export formats: JSON, CSV, and SQL
- Stdio npm package @mockherodev/mcp-server v0.1.3
- Requires MOCKHERO_API_KEY (free key at mockhero.dev)
- 156 field types and 22 locales per server description
- Export formats: JSON, CSV, SQL
- Package version 0.1.3; npm identifier @mockherodev/mcp-server
What problem does it solve?
Hand-built seed data is slow, unrealistic, and breaks when schemas or locales multiply during pre-release testing.
Who is it for?
Solo builders seeding Postgres or API integration tests who want agent-driven realistic data with SQL/CSV/JSON output.
Skip if: Builders who need production anonymization of real PII or who refuse a MockHero API key for generated fixtures.
What do I get? / Deliverables
After configuring MOCKHERO_API_KEY and the stdio server, your agent can produce locale-aware relational fixtures ready for databases or test suites.
- Realistic relational datasets in JSON, CSV, or SQL
- Locale-aware sample values across supported field types
- Agent-triggered fixture generation aligned to your schema needs
Recommended MCP Servers
Journey fit
Realistic test data is most critical in Ship when you prove the product works against representative loads and schemas before release. Testing subphase covers fixtures and seed data; MockHero’s 156 field types and locale-aware values directly support integration and E2E setup.
How it compares
API-backed synthetic data MCP, not an in-repo faker library skill with no export service.
Common Questions / FAQ
Who is MockHero MCP for?
Developers and solo founders who need believable multi-table test data and want their agent to request it through MCP instead of maintaining huge static JSON files.
When should I use MockHero MCP?
Use it in Ship testing when you are preparing staging seeds, demo datasets, or integration tests that need varied locales and many field types.
How do I add MockHero to my agent?
Install/configure the npm stdio server @mockherodev/mcp-server, set the required secret MOCKHERO_API_KEY from mockhero.dev, and register it in your MCP host.
