How-to guidesInstall a package into a manifest

Install a package into a manifest

Add new abilities to your agent from the marketplace. Give it a database client to inspect a schema, a browser to test a web page, or an MCP server for a service your team uses. A package is a tool, an agent, or an MCP server. An admin installs it for the organization, then you add it to your manifest.

Before you start

  • Role: admin or owner to install a package (step 1). Any member can browse the Marketplace and add an installed package to a manifest (step 2).
  • Available when your administrator enables the marketplace.
  • A manifest to add it to. See Create a manifest.

Steps

Step 1: install the package (admins and owners)

If the package is already installed, skip to step 2.

  1. In the left rail, open Marketplace.
  2. On the Browse tab, find the package. Use the search box (Search marketplace by name or tag…) or the category chips.
  3. Click Install followed by the version, for example Install 1.2.0. Use the version drop-down (Choose a version) to pick another one.
  4. If the package needs other packages, the dialog Install with dependencies lists them. Click the install button.
  5. If the package asks to inject a credential into its tools, the dialog Credential access for the package name opens. It lists each credential request with a switch to accept or deny it. Requests marked required cannot be denied. Requests marked optional start accepted. Click Install.

Step 2: add it to your manifest

  1. Open Manifests and click the manifest’s row to edit it.
  2. Click + Add package.
  3. In the picker, filter by name, description, or tool. Click each package you want to select it, or use Select all to pick every package in the filtered list and Select none to clear them. The picker lists the packages your admin allows you to add.
  4. Click the Add button at the bottom. It shows how many items you selected.
  5. If the package needs a credential, connect it on the Connections page. The manifest’s status on the list shows how many credentials are missing.
  6. Click Save.

What you should see

  • After step 1: the package on the Installed tab of the Marketplace.
  • After step 2: a card for the package in the manifest editor, under Agent, Integrations, AI Packages, or Configurations.
  • Spaces you create after saving include the package. Spaces that already exist do not change.

Next

Create a space from a manifest: start a fresh space and your agent has the new package.
