SandboxAPI is a Model Context Protocol (MCP) server: Execute code in 8 languages (Python, JS, TS, Go, Java, C++, C, Bash) in gVisor sandboxes. Because it speaks the Model Context Protocol, AI assistants can use SandboxAPI as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://mcp.sandboxapi.dev/mcp and you're connected, with nothing to install locally. The current release is v1.0.0, published under the MIT license, with source at sandboxapi/sandboxapi-mcp on GitHub.
On mcp.site, SandboxAPI sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
