Extend GitLab Duo Agent Platform: Connect any tool with MCP

GitLab Duo Agent Platform now supports MCP (Model Context Protocol), enabling developers to connect external tools like Jira directly to their AI-powered IDE environment. The tutorial covers setting up a Jira OAuth 2.0 application in the Atlassian Developer Console, configuring the MCP client via a `.gitlab/duo/mcp.json` file, and verifying the connection using the built-in MCP Dashboard in VS Code. Three practical workflows are demonstrated: sprint planning assistance (querying backlog, prioritizing issues), bug triage and issue creation from code context, and cross-system incident investigation correlating Jira tickets with GitLab merge requests. Security considerations including OAuth token management and least-privilege scopes are also addressed.
