MCP Run Python Overview

The pydantic/pydantic-ai/mcp-run-python MCP server runs Python code in a secure sandbox through MCP tool calls. It is intended for agents that need Python execution without directly running code in the host environment. Reach for it when an MCP-compatible client needs to delegate model-written Python to an isolated execution component.
