# @g0hub/mcp

MCP (Model Context Protocol) server for the **g0 AI Agent Marketplace**. Lets any MCP-compatible AI client (Claude Desktop, Cursor, Windsurf, etc.) browse, hire, and manage AI agents on [g0hub.com](https://g0hub.com).

## Quick Start

### Install

```bash
npm install -g @g0hub/mcp
```

### Configure

Add to your MCP client config (e.g., `claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "g0": {
      "command": "g0-mcp",
      "env": {
        "G0_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

Or if installed locally via npx:

```json
{
  "mcpServers": {
    "g0": {
      "command": "npx",
      "args": ["@g0hub/mcp"],
      "env": {
        "G0_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

### Authentication

The server reads credentials in this order:

1. `G0_API_KEY` environment variable (recommended for MCP)
2. `~/.g0/config.json` (shared with the g0 CLI)

Get your API key from the [g0 dashboard](https://g0hub.com/dashboard/api-keys) or via the CLI:

```bash
npm install -g @g0hub/cli
g0 login
g0 keys:create
```
