 ## MCP Server
 
-To make it easy to add these customizations to your editor, we have created a [MCP Server](https://developer.microsoft.com/blog/announcing-awesome-copilot-mcp-server) that provides a prompt for searching and installing prompts, instructions, and chat modes directly from this repository. You'll need to have Docker installed and running to run the server.
