Browse the catalog

The catalog is the main view of the Enterprise Cloud UI. It shows the MCP servers and skills available to you, filtered by your permissions. From here you can search, inspect a server's tools, and install it into Stacklok Desktop or directly into an AI client.

The Cloud UI has two catalog views, selectable from the navigation bar:

  • MCP Servers - the MCP servers published to your registries.
  • Skills - the agent skills published to your registries.

What you see in each view is filtered by your identity. The Registry Server returns only the resources your JWT claims authorize, so the catalog never shows servers or skills you can't access. See Claims-based visibility for details.

Browse MCP servers​

Select MCP Servers in the navigation bar to open the server catalog. The top of the page includes:

  • Registry selector - a dropdown to switch between the registries available to you. The Cloud UI defaults to the first available registry.
  • Search - full-text search across server names and descriptions.
  • View toggle - switch between Grid view (cards) and List view (a table).

Each server shows its name, description, and version. Servers that aggregate other servers are tagged with a Virtual MCP badge.

Server details​

Select a server to open its detail page. The header shows the server name, its publisher (the source it came from), and badges for the transport type, version, and any environment variables. A version selector lets you switch between available versions.

The detail page has two tabs:

  • About - the full server description, a View Repository link when the server declares a source repository, and a Getting started section with the server's endpoint URL (with a copy button) and the Add to client options.
  • Tools - a table of every tool the server exposes, with each tool's name and description.

If you have the entry management role, Edit and Delete buttons also appear on the detail page. See Manage entries.

Install a server in Stacklok Desktop​

The Install button opens Stacklok Desktop to the selected server's detail page. Under the hood, the button triggers a deep link using the stacklok-enterprise-gui:// protocol:

stacklok-enterprise-gui://v1/open-registry-server-detail?serverName=<NAME>

Stacklok Desktop receives this link and navigates to the server's detail page, where you can review and install the server. If Stacklok Desktop isn't installed, the Cloud UI shows a Desktop app required dialog prompting you to contact your administrator.

note

The enterprise protocol stacklok-enterprise-gui:// is separate from the open source toolhive-gui:// protocol, so both editions can coexist on the same machine.

Add a server to an AI client​

The Add to client dropdown offers one-click integration with supported AI clients. It's available on both the catalog list and the server detail page. The dropdown also includes a Copy URL option that copies the server's endpoint to your clipboard.

Cursor​

Opens Cursor with the MCP server pre-configured through a deep link:

cursor://anysphere.cursor-deeplink/mcp/install?name=<NAME>&config=<BASE64>

Visual Studio Code​

Opens VS Code with the MCP server pre-configured through a deep link:

vscode:mcp/install?<JSON_CONFIG>

Claude Code​

Copies a CLI command to your clipboard that you can paste into a terminal. For a remote server, the command looks like:

claude mcp add --transport http "<SERVER_NAME>" <URL>

Browse skills​

Select Skills in the navigation bar to open the skills catalog. Skills are agent skill packages published to your registries. The list shows each skill's name and description, with a link to its source repository and an Install button.

Select a skill to open its detail page, which shows:

  • Summary - the skill's description, with badges for its version, repository, and license.
  • SKILL.md - the rendered contents of the skill's definition file, so you can review what the skill does before installing it.

From the skill detail page you can:

  • Install - opens Stacklok Desktop to install the skill, using the same deep link mechanism as MCP servers:

    stacklok-enterprise-gui://v1/open-registry-skill-install?namespace=<NAMESPACE>&skillName=<NAME>

  • Download - downloads the skill package as a .zip archive so you can use it outside Stacklok Desktop.

  • View Repository - opens the skill's source repository.
