FAQ from PubMed MCP

How do I configure PubMed MCP?

Add the provided JSON snippet to your claude_desktop_config.json file, specifying the command uvx and arguments ["pubmedmcp@latest"].

What are the prerequisites?

You need uv installed with uvx available in your PATH, and Python 3.12 must be used (set via the UV_PYTHON environment variable).
