PlumberKit

PlumberKit is a GitHub Copilot Marketplace that contains many useful (plugins) tools for developers. Contains Agents, skills and MCP Server tested and ready to use.

I know this Marketplace is not the most complete you have seen in your life, but it is a good starting point to create your own plugins and share them with the community. I have created it to learn how to create plugins and share them with the community. I hope you enjoy it and if you want to contribute, please do it. I will be happy to review your pull requests and merge them.
