Required configuration to expose your Tool Server to the internet

As II-Agent use e2b as the sandbox provider, we hide our key credentials in a tool server that must be exposed to the internet to get access from the tool server

NGROK_AUTHTOKEN​

  1. Create an ngrok account (free tier works for development) and log in.
  2. Navigate to Getting Started → Your Authtoken.
  3. Copy the token string (2Hk...) and paste it into docker/.stack.env as NGROK_AUTHTOKEN.
  4. Keep the token secret; it grants access to your ngrok account limits.

NGROK_REGION​

  • Pick the region closest to your machine or the people testing with you. Common choices: us, eu, ap, au, sa, jp, in.
  • Check the ngrok region list if you need the full set.
  • Update the env variable whenever you move to a different geography to keep latency low.
