+### Launch Options
+
+You can customize Puppeteer's browser behavior in two ways:
+
+1. **Environment Variable**: Set `PUPPETEER_LAUNCH_OPTIONS` with a JSON-encoded string in the MCP configuration's `env` parameter:
+
+    ```json
+    {
+      "mcpServers": {
+        "mcp-puppeteer": {
+          "command": "npx",
+          "args": ["-y", "@modelcontextprotocol/server-puppeteer"]

+            "ALLOW_DANGEROUS": "true"
+          }
+        }
+      }
+    }
+    ```
+
+2. **Tool Call Arguments**: Pass `launchOptions` and `allowDangerous` parameters to the `puppeteer_navigate` tool:
+
+   ```json
+   {
+     "url": "https://example.com",
+     "launchOptions": {
+       "headless": false,
