Marketplace

The Marketplace lets you discover, install, and manage curated plugins that extend your agent with reusable skills, MCP servers, rules, and subagents.

Note

Cross-surface synchronization: Plugins installed in the Antigravity App are automatically updated and displayed in the Antigravity CLI’s Installed tab.

Browse and install plugins

To browse and install Marketplace plugins in the Antigravity App, follow these steps:

1. In the left sidebar, click the Customizations tab (below Automations):

   

2. Click the Marketplace tab to view available plugins:

   

3. Click any plugin card to inspect its details and bundled capabilities:

   

4. Click + on the plugin card to install it.

Configure plugin credentials (API keys and OAuth)

Some plugins connect to external services that require authentication before their MCP tools can run:

• API tokens and configuration variables: If a plugin requires an API key, token, or workspace URL, toggling the plugin on in Customizations > Installed opens a setup dialog prompting for each variable (with a direct link to generate or look up your token).
• OAuth sign-in: If a plugin uses OAuth 2.0, Antigravity opens your browser to complete sign-in when the plugin’s MCP server connects.

Manage installed plugins

To inspect, toggle, or uninstall existing plugins:

1. In the Customizations panel, click the Installed tab:

   

2. Click the ⋮ menu beside any installed plugin (or open the plugin card) to enable, disable, or configure it.

3. Select Uninstall from the ⋮ menu (or on the plugin detail page) to remove a plugin.

Any plugins you install in the Antigravity App automatically sync and appear in the Antigravity CLI’s Installed tab.

Discover tab

Use the Discover tab to browse the Marketplace catalog and install new plugins:

• Search plugins: Start typing to search and filter for specific plugins.
• Install from a local directory: Highlight Install from local directory and press Enter to provide a local filesystem path for plugin installation.
• View plugin details: Highlight a plugin and press Enter to expand its details view. The details view displays the following information:
  • Description
  • Included components (MCP servers, skills, rules, agents, and more)
  • Marketplace name
  • Version
• Install or uninstall: Press Ctrl + S on an uninstalled plugin to install it, or press Ctrl + S on an installed plugin to uninstall it.

The following example shows the Discover tab with the details of a selected plugin expanded:

After installation

Once a plugin is installed, the interface updates as follows:

• Discover tab: A green dot (●) appears beside the plugin name indicating its installed status.
• Installed tab: The plugin name appears in the Installed tab list.

Installed tab

Use the Installed tab to inspect and manage the plugins you have installed:

• Search installed plugins: Start typing to filter your installed plugins.
• Enable or disable: Press Space on an installed plugin to toggle it between enabled and disabled. If the plugin declares required MCP credentials (variables), pressing Space opens an interactive prompt to fill in those values before enabling the plugin.
• View plugin details: Press Enter on an installed plugin to expand its details view. The details view displays the following information:
  • Description
  • Skills (if applicable)
  • MCP servers (if applicable)
  • Rules (if applicable)
  • Agents (if applicable)
  • Marketplace name
  • Local installation path
  • Version
• Uninstall: Press Ctrl + S on an installed plugin to uninstall it.

Inline /plugin commands

In addition to the interactive panel, /plugin supports inline commands to install, uninstall, enable, disable, and list plugins directly from the prompt without opening the plugin manager UI:

• Install from the official marketplace or a local directory: Run the following commands (<marketplace-name> supports the official marketplace, antigravity-plugins-official):

  /plugin install <plugin-name>@antigravity-plugins-official
  /plugin install <local-path>

  For example, running /plugin install firebase@antigravity-plugins-official outputs:

  Successfully installed plugin "firebase" from "antigravity-plugins-official".

• Manage and list plugins inline: Run the following commands:

  /plugin uninstall <plugin-name>
  /plugin enable <plugin-name>
  /plugin disable <plugin-name>
  /plugin list

---

Install from your shell (agy plugin)

Outside an interactive TUI session, you can install and manage plugins directly from your shell using agy plugin:

• Install from the official marketplace: Once signed in to agy, specify <plugin-name>@antigravity-plugins-official (<marketplace-name> only supports the official marketplace, antigravity-plugins-official), or pass a bare <plugin-name>, which defaults to <plugin-name>@antigravity-plugins-official:

  agy plugin install firebase@antigravity-plugins-official
  agy plugin install firebase

  Running either command outputs:

  Installed plugin "firebase" from antigravity-plugins-official

• Install from a GitHub link: Clone and stage a plugin directly from a GitHub repository URL:

  agy plugin install https://github.com/<owner>/<repo>

• Install from a local directory: Stage a local plugin folder into your profile:

  agy plugin install </path/to/local/plugin>

• List installed plugins: Run agy plugin list for a human-readable summary of installed plugins and their component counts, or pass --json to output a JSON array with installation paths and component names:

  agy plugin list
  agy plugin list --json

• Enable, disable, or uninstall plugins:

  agy plugin enable <plugin-name>
  agy plugin disable <plugin-name>
  agy plugin uninstall <plugin-name>

Using installed plugins

Once a plugin is installed and enabled, its bundled capabilities are available in your workspace automatically:

Component	How to use it in your workflow
Starter prompts	In the Antigravity App (Customizations > Installed), open a plugin’s detail view and click any suggested prompt chip to start a guided task immediately.
Skills	Ask for a task in natural language—Antigravity loads relevant plugin skills on demand using progressive disclosure—or invoke a skill explicitly in chat with /<skill-name>.
MCP servers	Ask the agent to query or act on the connected service (such as Jira, Figma, Datadog, Stripe, or Firebase). Bundled MCP tools (namespaced as <plugin-name>_<server-name>) are available automatically while the plugin is enabled.
Custom agents & subagents	The main agent delegates specialized tasks (such as security reviews or accessibility audits) to bundled subagents automatically. You can also run a plugin’s custom agent directly as your primary session agent via the agent selector in the App, /agents in the CLI, or agy --agent <agent-name> from your terminal (run agy agents to list all available agents).
Rules & Hooks	Run automatically in the background while the plugin is enabled—enforcing coding conventions, SDK standards, and pre- or post-tool policy checks without manual invocation.
