This skill addresses the challenge of securely executing arbitrary code with AI during development. In practice, developers often need AI assistants to run scripts, test code snippets, or execute terminal commands, but direct execution poses security risks—malicious code could compromise the environment or leak data. The 302AI Sandbox MCP Server provides an isolated sandbox environment, allowing AI to run code safely within a controlled container without worrying about system security.
Usage is straightforward: you simply obtain a 302AI API Key and start the MCP service via the npx command. After that, you can use natural language instructions to have the AI execute code in the sandbox, create/destroy sandboxes, import/export files, run command lines, and more. It supports dynamic loading of the tool list; the remote server automatically updates available tools, eliminating the need for manual configuration. You can also choose between local stdin mode or remote HTTP server mode, flexibly adapting to different scenarios.
It is ideal for teams or individuals who need AI assistants to execute code securely. This is especially true for developers already using MCP clients like Claude Desktop, Cherry Studio, or ChatWise, who want AI to write, run, and debug code. Agent developers can use it to build agents that autonomously execute tasks, backend developers can use it to quickly validate algorithms, and test engineers can use it to run automated test scripts.
It is recommended to consistently use this sandbox whenever AI needs to execute any untrusted code. Note that it relies on a remote API service, requiring a network connection, and the sandbox environment is subject to the remote server's resource quotas. It is advisable to set appropriate API Key permissions during configuration to avoid excessive consumption. Additionally, while sandbox execution results are returned to the AI, sensitive data should be avoided from being passed directly into the sandbox.
Key Features
Unlike e2b's code sandbox, the 302AI Sandbox MCP Server supports automatic updates to the dynamic tool list, eliminating the need for manual registration of new tools. It also offers both stdin and HTTP dual modes, enabling low-latency local operation or deployment as a remote service for shared use by multiple users.
Limitations
Requires a 302AI API Key for use. The sandbox environment depends on a remote server and is subject to API rate limits. Fully offline operation is not supported.
FAQ

Which programming languages are supported?
The sandbox supports multiple languages, depending on the remote server configuration. Common languages like Python, JavaScript, and Shell are typically included.
