What is the Gru Sandbox MCP server?

Gru Sandbox becomes available to MCP clients through the gru sandbox mcp server. Gru-sandbox(gbox) is an open source project that provides a self-hostable sandbox for MCP integration or other AI agent usecases.

What Gru Sandbox does

This installs just the GBOX CLI. Additional dependencies (like ADB, frpc, Appium) will be automatically installed when needed, or you can install them later using: bash gbox setup

Tools it exposes

Once connected, the assistant can call these 3 tools directly:

  • Prerequisites — The Prerequisites tool exposed by this server
  • Build — The Build tool exposed by this server
  • Contributing — We welcome contributions! Please feel free to submit a Pull Request. For major changes, please open an issue first to discuss what you would like to change

Installing the gru sandbox mcp server

The server is distributed via npm as @gbox.ai/cli, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Requirements

  • Go 1.21 or later - Make - pnpm (via corepack) - Node.js 16.13 or later

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Gru Sandbox sits in that group, and the shape of its toolset — Prerequisites, Build, Contributing — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Written in Go.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the gru sandbox mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
