maxim-saplin/mcp_safe_local_python_executor

Overview

A stdio MCP server that wraps the LocalPythonExecutor from Hugging Face's smolagents framework. It provides a Python runtime that is easier to set up than Docker, VM, or cloud alternatives, while restricting allowed operations and imports to enforce safety.

Best for

Best for
Developers who need basic safe local execution of Python code in MCP-based workflows

Use cases

• Execute untrusted Python snippets locally without full sandboxing overhead
• Integrate safe code execution into MCP-based tools and agents
• Protect host systems by limiting imports and operations in ad-hoc scripts

Use cases

• Execute untrusted Python snippets locally without full sandboxing overhead
• Integrate safe code execution into MCP-based tools and agents
• Protect host systems by limiting imports and operations in ad-hoc scripts

Pros

• Lightweight setup compared to Docker or remote runtimes
• Built-in restrictions reduce risk from malicious or buggy code
• Leverages a proven framework from Hugging Face

Cons

• Not a full sandbox; sophisticated attacks may bypass restrictions
• Limited to a single machine; no multi-node or distributed execution
• Few stars and contributors indicate a small community
