The Multiple Project Summary Reporting Standard, also known as cctray.xml or cc.xml, is an XML feed format initially developed by ThoughtWorks for CruiseControl.net to provide an RSS-like continuous integration (CI) service build status. This format has since been adopted by various CI services and can be accessed on platforms like Buildbox by using a specific URL format that includes the account name and API key, which can be obtained from the user's account settings. Users can customize the feed to monitor specific branches by appending the branch name to the URL. The feed is compatible with several desktop clients, including CCMenu for OS X and CCTray for Windows, allowing users to easily track the status of their builds.
