Copilot Spaces is a new feature introduced by GitHub that enhances collaboration among developers by providing a shared workspace to work with code and context. This feature allows teams to organize their projects more effectively and improves the coding experience with real-time collaboration tools. Users can interact with code in a more contextual manner, making it easier to understand and manage complex projects.

A collection of system prompts, messages, and developer notes is available for public access, encouraging contributions through pull requests. Users can also star the repository to track its history and updates.

The GitHub team discusses their decision to open-source their MCP server, highlighting the benefits it brings to the community, such as increased collaboration and transparency. They aim to encourage contributions from developers to enhance the server's functionality and improve its overall performance.
