Add Image from MCP Registry
On the main screen, you can add images for MCP servers based on MCP Registry. MCP Registry is a centralized directory for Model Context Protocol (MCP) servers. It provides a catalog of available MCP servers along with their details, allowing you to easily discover and integrate MCP servers into your DIAL environment.
To add a new image
- Click the Add button on the main screen and select From MCP Registry.
- In the Add Image from MCP Registry form, populate the required fields and click Add to add the image.
| Field | Required | Description |
|---|---|---|
| Name | Yes | Name of the image. |
| Version | Yes | Version of the image. |
| Description | No | Brief description of the image. |
| MCP server name | Conditional | Name of MCP server from the MCP Registry. Start typing in the text box to search for available MCP servers or click Select from registry to display a window with a list of available MCP servers and their details. |
| Source type | Conditional | Use Source type to choose how to install an image in case the selected MCP has both source code repository and Open Container Initiative (OCI) package available. Available values: - Docker Image: To deploy from the Docker image specified in the OCI package. - Source Code: To deploy from the source code repository. Click Select from registry and open server details to find all this information. |
| Branch name | Conditional | The name of the branch in the source code repository. Available if Source type=Source Code. |
| SHA | Conditional | The SHA in the source code repository that uniquely identifies each commit in the repository’s history. This SHA is a 40-character hexadecimal string generated by Git whenever you make a commit. Available if Source type=Source Code. |
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 | Create a new image version or display configuration of a selected version. Versioning logic: - If creating a new image with a new name, the default version is 1.0.0. - If the new name already exists, the version is patch-bumped from the highest existing version for that name. - For new versions of the same name, the version is patch-bumped from the current image name’s highest version. |
| Save / Save as new version / Save as new image | The available save action depends on your changes: - Save: For installed images, if you only update Description, Maintainer, or Topics. - Save as new image: If you change the Name of the image. The dialog title will be Save new image. - Save as new version: If you keep the Name but want to create a new version. The dialog title will be Save new version.  |
| Create Interceptor/MCP/Adapter/Application Container | Enabled for installed images. Use to create a new MCP, Adapter, Application or Interceptor container based on the selected image. |
| Install / Stop | - Install: Install is enabled for images not yet installed. Click to install the selected version. - Stop: During installation, Stop appears and can be used to interrupt the process. |
| Delete | Use to delete the selected image. Note: Deleting an image affects related containers. |

Read-only and auto-populated for images created from MCP Registry.- Branch name: Name of the branch in the source code repository. - SHA: SHA in the source code repository that uniquely identifies each commit in the repository’s history. This SHA is a 40-character hexadecimal string generated by Git whenever you make a commit. - Base directory: Directory path with the Docker file. If provided, must not start or end with /. |
| MCP server name | Conditional | Yes | Name of MCP server from the MCP Registry. Start typing in the text box to search for available MCP servers or click Select from registry to display a window with a list of available MCP servers and their details. Applies only to MCP type of image. |

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, Application 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.
Audit
In the Audit tab, you can review activity, usage, and operational metrics for the selected image version, including build and configuration change history.
Note: This tab mimics the functionality available in the global Activity section, but is scoped specifically to the selected image.
