JsonFabrica MCP server

This is a small helper that connects your AI assistant to JsonFabrica, a service that makes fake but realistic JSON test data. Once it is set up, you can ask your AI to build sample customers, orders, or any other records and it will do it for you. It is handy if you write code or test software and need example data without making it by hand.

What this MCP server does

You ask your AI for some test data, like twenty customers and sixty orders. The AI uses this helper to talk to JsonFabrica, which builds the records from templates you or the AI set up. The data comes back as JSON, which is just a text format for structured information. If you asked for a file, the AI can save it where you want. You get realistic sample data without typing it all out.

What you can do with it

• Create templates that describe the shape of your data
• Generate single records or whole batches of linked records
• List, update, and delete templates you have saved
• Manage sequences, like order numbers that count up
• Check your account usage
• Check that the connection to JsonFabrica works

Try asking your AI

• “Generate 20 realistic customer records and save them to fixtures/customers.json”
• “Make 50 orders that each link to one of the customers you just created”
• “Show me all my saved templates”
• “How much of my JsonFabrica usage have I used this month?”

What it gives back to you

You get JSON data back in the chat, either as a single record or a list of records. If you asked for a file, the AI writes it to the path you gave. Some actions, like listing templates or checking usage, return short summaries or numbers. When the AI changes something, like updating a template, it tells you what it did.
