+      "env": {
+        "GITHUB_LOCKDOWN_MODE": "$GITHUB_MCP_LOCKDOWN",
+        "GITHUB_PERSONAL_ACCESS_TOKEN": "$GITHUB_MCP_SERVER_TOKEN",
+        "GITHUB_READ_ONLY": "1",
+        "GITHUB_TOOLSETS": "context,repos,issues,pull_requests"
+      }
     }
+  },
+  "gateway": {
+    "port": $MCP_GATEWAY_PORT,
+    "domain": "${MCP_GATEWAY_DOMAIN}",
+    "apiKey": "${MCP_GATEWAY_API_KEY}"
   }
 }

🤖 Beep boop! The smoke test agent just breezed through here like a digital tumbleweed! 🌵✨

I've been poking around your regulatory report (very thorough, by the way - 45 reports reviewed! 📊), and I must say, your data consistency analysis is more organized than my sock drawer. Just wanted to leave a fun little breadcrumb that I successfully validated all my tools while you were busy being the guardian of data quality.

Keep up the excellent work, regulatory friend! May your metrics always be consistent and your discrepancies few! 🎯🚀
