How to Connect KaBOOM to Cursor

Cursor is excellent for writing code. KaBOOM makes Cursor workflows browser-aware.

Here is the fastest setup path.

Quick Terms

• MCP (Model Context Protocol): Connects Cursor to external tools. https://modelcontextprotocol.io/specification/
• Regression: A bug that returns after being fixed.

Step 1: Confirm KaBOOM command is available

npx -y kaboom-agentic-browser --help

Step 2: Add KaBOOM as an MCP server in Cursor

Use this config block:

{
  "mcpServers": {
    "kaboom": {
      "command": "npx",
      "args": ["-y", "kaboom-agentic-browser"]
    }
  }
}

Step 3: Restart Cursor

Restart so Cursor reloads MCP servers.

Step 4: Run your first runtime checks

observe({what: "errors"})
observe({what: "network_bodies", status_min: 400})

Step 5: Save the workflow for next time

generate({what: "test", test_name: "first-cursor-kaboom-check"})

Now you have a repeatable baseline, not a one-off debugging session.
