KaBOOM + Zed

KaBOOM is an open-source MCP server that gives Zed’s AI assistant access to browser console logs, network errors, exceptions, WebSocket events, and live DOM state. Zero dependencies.

Auto-Install

kaboom-agentic-browser --install zed

Manual Configuration

Add to ~/.config/zed/settings.json:

{
  "context_servers": {
    "kaboom": {
      "source": "custom",
      "command": "kaboom-agentic-browser",
      "args": []
    }
  }
}

If using npx:

{
  "context_servers": {
    "kaboom": {
      "source": "custom",
      "command": "npx",
      "args": ["-y", "kaboom-agentic-browser"]
    }
  }
}

Zed uses context_servers instead of mcpServers, and entries require "source": "custom" for manually configured servers.

Usage

After restarting Zed, the AI assistant taps into KaBOOM’s full MCP toolset.

Troubleshooting

1. Restart Zed after editing settings
2. Check the config key — must be context_servers
3. Verify the KaBOOM extension popup shows “Connected”
