#38 - Add notes about full paths for commands

[alexfinnarn]

Trying to fix people's confusion when the full path to the command is not used, like #38

Motivation and Context

I could not use Claude Desktop with MCP servers until I made this change.

How Has This Been Tested?

I have tested this change locally in my claude_desktop_config.json. When just listing npx I had errors. Once I added the full path to npx the MCP sever tools showed up.

Breaking Changes

No, if users' environments currently work, they will work without making this change. It simply makes the path to commands more explicit.
