# 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}" ] } } } ``` ### Cu…
