Situation

There are plenty of references for generating and using SSH keys on MacOS. Google for answers and they're everywhere. What is less obvious is how to use multiple SSH keys, especially for the same host, e.g. GitHub. I had multiple SSH keys and a ~/.ssh/config file, but certain of the credentials weren't being found.

Solution

The nuggets of goodness I found describe how to properly use ~/.ssh/config - (here, here, here, here... +many more). The key is actually using the resulting Host aliases!

Go figure, huh? 🤦

Example: Github - SourceTree

Claude MCP - with NVM

As documented by Jonathan Gastón Löwenstern (hereafter, JGL), loading Claude Desktop MCP servers while using Node Version Manager (NVM) can be fraught, and there is little assistance in the community. Thankfully, Jonathon describes and solves the problems.

My modification is the ability to configure and use an NVM alias for use with Claude MCPs, without hardcoding the node version.

Caveats: This is tested and known to work on MacOS Monterey with ZSH. I have not tried other flavors of MacOS, Linux, or shells.
