Global firewall
Global firewall settings define an allow list of authorized domain names for all image builds in the environment. This helps operators avoid duplicating common allowed domains across images. Individual image allow lists can extend the global list.
Domain name requirements: Enter the domain name without protocol, e.g., github.com. Each domain must have at least one dot, labels can include letters, numbers, and hyphens (1–63 chars, not starting or ending with a hyphen), and the top-level domain must be at least 2 letters. Domain name must not include leading or trailing hyphens in labels.
Configuration
Click any image from the main screen to open its configuration screen.
On the configuration screen, you can view and edit the selected image settings.
Actions
In the header of the Configuration screen, you can find the following action buttons:
| Action | Description |
|---|---|
| Version | Click to create a new image version or display configuration of a selected version. |
| Create Interceptor/MCP/Adapter Container | Enabled for the installed images. Click to create a new MCP, Adapter or Interceptor container based on the selected image. |
| Install | Enabled for not installed images. Click to install the selected version of an image. |
| Delete | Click to delete the selected image. Note: Deleted image will effect the related containers. |
Properties
In the Properties tab, you can preview and modify selected image's basic properties.
| Field | Required | Editable | Description |

Advanced users with technical expertise can work with image properties in the table or a JSON editor view modes. It is useful for advanced scenarios of bulk updates, copy/paste between environments, or tweaking settings not exposed on UI.
Firewall settings
The allow list domains setting specifies which external resources the image build process can access. These settings are relevant only while the image is being created—for example, to control which domains or repositories can be reached when installing dependencies or downloading files.
Note: Firewall settings defined for a specific image apply in addition to the Global firewall settings.
Note: These firewall rules do not affect containers that are later created from the image. Containers can have their own firewall settings.
Domain name requirements: Enter the domain name without protocol, e.g., github.com. Each domain must have at least one dot, labels can include letters, numbers, and hyphens (1–63 chars, not starting or ending with a hyphen), and the top-level domain must be at least 2 letters. Domain name must not include leading or trailing hyphens in labels.
Related Containers
This tab is enabled for installed images.
The Related Containers tab displays all MCP, Adapter or Interceptor containers related to the selected version of the image.
Add containers
You can link containers to this image or a specific version of it. When you add a container here, it will automatically use the selected image version in its configuration.
Note: Every container must be linked to an image or image version. Once linked, you cannot remove the container from this list—you can only change which image it uses.
- Click Add to invoke the adding modal.
- In the modal, you can enable/disable the Show containers related to this image toggle to display all containers or containers associated with all versions of the selected image.
- Select one or several containers and click Apply. Important: Running containers will be restarted with the new image.
Installation log
This tab is enabled for installed images.
The Build Log tab displays the complete output generated during the image build process. Here you can view the step-by-step execution of build instructions, including command outputs, warnings, and errors that occurred during image creation.
