+## Chrome DevTools (Browser Automation)
+
+The project uses `@vibebrowser/chrome-devtools-mcp` from `github.com/dzianisv/chrome-devtools-mcp`. It runs an MCP server over HTTP/SSE, allowing multiple agents to connect remotely.
+
+**No `--remote-debugging-port` needed.** The daemon discovers Chrome via `--autoConnect` (reads `DevToolsActivePort` file). Port is discovered automatically.
+
+**Local Copilot CLI config** (in `.github/copilot-mcp.json` or IDE MCP settings):
+```json
+{
+  "chrome-devtools": {
+    "type": "remote",
+    "url": "http://localhost:9333/mcp",
+    "enabled": true
+  }
+}
+```
+
+**Starting the daemon:**
+```bash
+chrome-devtools start --autoConnect --port 9333
+```
