Cursor setup - Synthbrew

Use the Synthbrew MCP server in Cursor Agent to create realistic demo data sources while coding your app.

Prerequisites

Cursor installed
A Synthbrew public API key

Configure Cursor

Create .cursor/mcp.json in your project, or ~/.cursor/mcp.json for a global setup:

{
  "mcpServers": {
    "synthbrew": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@synthbrew/agent"],
      "env": {
        "SYNTHBREW_API_KEY": "sb_api_...",
        "SYNTHBREW_API_URL": "https://api.synthbrew.com/api"
      }
    }
  }
}

Restart Cursor or reload MCP servers after changing the file.

Try a product prompt

Open Cursor Agent and ask:

Use Synthbrew to create a marketplace dataset with sellers, buyers, products, orders, reviews, and refunds. Generate realistic data, create the source, and show me how to connect to it from this app.

Cursor should validate the schema before creating resources.
