YouTrack MCP is a Model Context Protocol server that exposes YouTrack functionality to MCP clients and AI assistants. It enables seamless interaction with YouTrack's issue tracking system through simple, structured operations such as creating, reading, updating, and deleting issues; retrieving and managing projects and custom fields; performing advanced searches; managing users and permissions; handling attachments up to 10MB; and leveraging the full YouTrack REST API. The server is designed to work with Claude Desktop and other MCP clients, enabling natural language-driven workflows like triage, prioritization, assignment, time estimation, and commenting. It demonstrates common operations like updating state and priority using simple strings, along with complete workflows for triage, feature development, and task completion. The project provides Docker images and npm packaging for easy deployment, supports multiple architectures (ARM64/Apple Silicon and AMD64), and includes documentation, tests, and automation scripts. It highlights robust configuration via environment variables (YOUTRACK_URL, YOUTRACK_API_TOKEN, YOUTRACK_VERIFY_SSL). It emphasizes comprehensive API coverage, error handling, and scalable custom fields management with ongoing test coverage.
