Mac Python version issues hinder Claude Desktop integration

By PulseAugur Editorial · [1 sources] ·

A developer encountered issues with their Mac's Python version while setting up an MCP server to integrate Oura Ring data with Claude Desktop. The system's default Python 3.9.6 was too old for the MCP Python SDK requirements, which specify Python 3.10 or higher, with the current SDK needing 3.11+. The developer recommends installing a newer Python version alongside the system Python, creating a virtual environment, and configuring Claude Desktop to use the new interpreter's absolute path. They also note that Homebrew upgrades can break existing environments, requiring a rebuild, and advise against writing to standard output in STDIO servers to avoid corrupting communication with Claude Desktop.
