Installation

This project provides a Model Context Protocol (MCP) server for YouTrack, enabling seamless integration with Claude Desktop and other MCP clients.

Quick Start

Using Docker (Recommended)

Choose from multiple registries:

Docker Hub (Primary)

# Use the latest stable release
docker run --rm \
  -e YOUTRACK_URL="https://your-instance.youtrack.cloud" \
  -e YOUTRACK_API_TOKEN="your-token" \
  tonyzorin/youtrack-mcp:latest

# Or use the latest development build
docker run --rm \
  -e YOUTRACK_URL="https://your-instance.youtrack.cloud" \
  -e YOUTRACK_API_TOKEN="your-token" \
  tonyzorin/youtrack-mcp:1.1.2_wip

GitHub Container Registry (New)

# Use the latest stable release
docker run --rm \
  -e YOUTRACK_URL="https://your-instance.youtrack.cloud" \
  -e YOUTRACK_API_TOKEN="your-token" \
  ghcr.io/tonyzorin/youtrack-mcp:latest

# Or use the latest development build
docker run --rm \
  -e YOUTRACK_URL="https://your-instance.youtrack.cloud" \
  -e YOUTRACK_API_TOKEN="your-token" \
  ghcr.io/tonyzorin/youtrack-mcp:1.1.2_wip

Available Docker Tags

Both registries provide identical tags:

• latest - Latest stable release (currently 1.1.2)
• 1.1.2 - Specific version tags
• 1.1.2_wip - Work-in-progress builds from main branch
• pr-<number> - Pull request builds for testing

Note: Images are now published to both Docker Hub and GitHub Container Registry simultaneously.

Using npm Package

Choose from multiple registries:

npmjs.org (Primary)

# Install globally
npm install -g youtrack-mcp-tonyzorin

# Or use with npx (no installation required)
npx youtrack-mcp-tonyzorin

GitHub Packages (New)

# Configure GitHub registry
npm config set @tonyzorin:registry https://npm.pkg.github.com

# Install globally
npm install -g @tonyzorin/youtrack-mcp

# Or use with npx
npx @tonyzorin/youtrack-mcp

• Test Coverage: 41% (continuously improving)
• CI/CD Pipeline: Automated testing and Docker builds
• Quality Assurance: Automated testing on every commit

For development instructions, see the Automation Scripts Guide and Release Process.

Configuration

Environment Variables

• YOUTRACK_URL: Your YouTrack instance URL
• YOUTRACK_API_TOKEN: Your YouTrack API token
• YOUTRACK_VERIFY_SSL: SSL verification (default: true)
• DISABLED_TOOLS: Comma-separated list of tools to disable (denylist mode)
• ENABLED_TOOLS: Comma-separated list of tools to enable (allowlist mode)

Tool Filtering

You can reduce context pollution and token usage by filtering which tools are available:

Denylist Mode - Disable specific tools:

export DISABLED_TOOLS="create_issue,update_issue,delete_page"

Allowlist Mode - Enable only specific tools (disables all others):

export ENABLED_TOOLS="get_issue,search_issues,get_projects"

Notes:

• Tool names are case-insensitive (Get_Issue = get_issue)
• Hyphens and underscores are equivalent (get-issue = get_issue)
• If ENABLED_TOOLS is set, it takes precedence over DISABLED_TOOLS
• Invalid tool names generate warnings but don't cause errors
• Filtering happens at startup for maximum efficiency

Example Configuration

export YOUTRACK_URL="https://prodcamp.youtrack.cloud/"
export YOUTRACK_API_TOKEN="perm-YWRtaW4=.NDMtMg==.JgbpvnDbEu7RSWwAJT6Ab3iXgQyPwu"
export YOUTRACK_VERIFY_SSL="true"
