Alpic automatically provides system environment variables to your MCP server deployments. These variables are set automatically and cannot be overridden by users.

​
System environment variables

​
ALPIC_HOST

Available at: Both build and runtime The hostname of your environment’s MCP server URL. Used internally to treat the deployed host as an internal host (like localhost) when it’s used as the OAuth server. 
ALPIC_HOST=server-123456.alpic.live

​
ALPIC_CUSTOM_DOMAINS

Available at: Both build and runtime A comma-separated list of custom domains that are configured for your environment. Used internally to treat the deployed host as an internal host (like localhost) when it’s used as the OAuth server. 
ALPIC_CUSTOM_DOMAINS=yourdomain.com,anotherdomain.com
