      "args": [
        "/path/to/bridge.js",

Open a Roo Code task in Code or Architect mode. Type a request that uses your tools — Roo Code will call them automatically and show you the result before proceeding.

Roo Code vs Cline — which should I use?

Both use identical MCP config. Roo Code adds extra agent modes (Architect for planning, Debug for troubleshooting) and some UX improvements. Try both — the config is compatible either way.
