Claude MCP error python version

mcp-uv-python-error-version.md

If you are creating a MCP in python using UV and when running in Claude have this error or related:

  × No solution found when resolving `--with` dependencies:
  ╰─▶ Because the current Python version (3.9.6) does not satisfy Python>=3.10
      and you require mcp[cli], we can conclude that your requirements are
      unsatisfiable.

You just need to run in your project this command:

uv python install 3.13 # or the desired version

And that's it.
