KaBOOM + OpenCode

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

Auto-Install

kaboom-agentic-browser --install opencode

Manual Configuration

Add to ~/.config/opencode/opencode.json:

{
  "mcp": {
    "kaboom": {
      "type": "local",
      "command": ["kaboom-agentic-browser"],
      "enabled": true
    }
  }
}

OpenCode uses the mcp key (not mcpServers) and expects command as an array.

Usage

After configuring, OpenCode can access KaBOOM’s full MCP toolset.

Troubleshooting

1. Restart OpenCode after editing config
2. Check the config key — must be mcp, not mcpServers
3. Verify the KaBOOM extension popup shows “Connected”
