The Atlassian Data Center MCP project provides integrations for Atlassian's Jira, Confluence, and Bitbucket Data Center products, enabling AI assistants to interact with these platforms through the Model Context Protocol. It allows for functionalities such as searching, viewing, and creating Jira issues, accessing and managing Confluence content, and interacting with Bitbucket repositories and code, ultimately bridging the gap between Atlassian's collaboration tools and modern AI workflows.
