### Description (declared)

# OpenSandbox MCP Sandbox Server

## 1. Overview

OpenSandbox MCP Server exposes the OpenSandbox Python SDK as MCP tools for Claude Code, Cursor, and other MCP-capable clients. It provides focused sandbox lifecycle management, command execution, and text file operations.

## 2. Installation & Startup

### Source

```bash
uv sync
uv run opensandbox-mcp
```

### Package

```bash
pip install opensandbox-mcp
opensandbox-mcp
```

### Configuration

Environment variables:

- `OPEN_SANDBOX_API_KEY`
- `OPEN_SANDBOX_DOMAIN`

CLI overrides:

```bash
opensandbox-mcp --api-key ... --domain ... --protocol https
```

Config fields:

- `api_key`: OpenSandbox API key for authentication.
- `domain`: OpenSandbox API domain, for example `api.opensandbox.io`.
- `protocol`: `http` or `https` for API requests.
- `request_timeout_seconds`: HTTP request timeout in seconds.
- `transport`: `stdio` by default, or `streamable-http`.
- `use-server-proxy`: when present, forces the SDK client to use server proxy mode.

### Streamable HTTP

```bash
opensandbox-mcp \
  --transport streamable-http \
  --host 0.0.0.0 \
  --port 8000
```

The HTTP transport defaults to `127.0.0.1:8000`. Set `--host 0.0.0.0` when the MCP server must be reached from another container, and use `--port` to select a different listening port. Keep the default loopback host unless the container network or an upstream gateway protects the exposed endpoint.

## 3. Integrations

### Claude Code stdio

```bash
claude mcp add opensandbox-sandbox --transport stdio -- \
  opensandbox-mcp --api-key "$OPEN_SANDBOX_API_KEY" --domain "$OPEN_SANDBOX_DOMAIN"
```

### Claude Code http

```bash
claude mcp add opensandbox-sandbox --transport http http://localhost:8000/mcp
```

### Cursor stdio

```json
{
  "mcpServers": {
    "opensandbox-sandbox": {
      "command": "opensandbox-mcp",
      "args": [
        "--api-key",
        "${OPEN_SANDBOX_API_KEY}",
        "--domain",
        "${OPEN_SANDBOX_DOMAIN}"
      ]
    }
  }
}
```
