RRunno Code SandboxThe @runno/mcp server provides a run_code tool that AI assistants can use to execute code snippets in various programming languages. It leverages the @runno/sandbox package, which uses WebAssembly to create isolated environments for code execution. The result of the code execution is provided over STDIO.

MCP code execution tool CMDEXEC_010

Detects MCP tools that execute arbitrary code

run_code

FIX

Restrict code execution tools to specific languages and sandbox the runtime environment. Use a container or VM-based sandbox instead of running code directly on the host.

FP?

Likely FP if the MCP tool is a dedicated code runner (e.g., Jupyter kernel) with documented sandboxing and no network access.
