ipybox: ipybox is a Python code execution sandbox with first-class support for programmatic MCP tool calling. It generates typed Python tool APIs from MCP server tool schemas, supporting both local stdio and remote HTTP servers. Code executes in a sandboxed IPython kernel with MCP tool call approval for security.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
