# Claude Desktop Extension

> Browse, purchase, and install skills directly in Claude Desktop

## Overview

The AgentPowers Claude Desktop extension brings the full marketplace
experience into Claude Desktop. Browse skills, read reviews, purchase
with Stripe, and install to any supported platform — all without
leaving your conversation.

## Installation

The recommended way to set up the AgentPowers extension is via the CLI setup command,
which auto-configures MCP for all detected AI tools (including Claude Desktop):

```bash theme={null}
npx @agentpowers/cli setup
```

<Accordion title="Legacy: .mcpb install (deprecated)">
  The `.mcpb` bundle install method is deprecated in favor of `npx @agentpowers/cli setup`.

  1. Download `claude-extension.mcpb` from the
     [latest release](https://github.com/AgentPowers-AI/claude-extension/releases)
  2. Drag the file into Claude Desktop, or double-click it
  3. Click **Install** when prompted
</Accordion>

No terminal or manual configuration required with the setup command.

## Usage

After installation, use natural language to interact with the marketplace:

* "Search AgentPowers for productivity skills"
* "Show me details and reviews for the code-review skill"
* "Buy the premium debugging skill"
* "Install my purchased skill for Kiro"
* "What skills do I have installed?"
