# YouTrack MCP

A Model Context Protocol (MCP) server that provides access to YouTrack functionality.

## 🚀 Quick Reference - Common Operations

### **🎯 State Transitions (Most Common)**
```python
# ✅ PROVEN WORKING FORMAT - Use simple strings
update_issue_state("DEMO-123", "In Progress")
update_issue_state("PROJECT-456", "Fixed")
update_issue_state("TASK-789", "Closed")

# ❌ DON'T USE - Complex objects fail
# update_custom_fields(issue_id, {"State": {"name": "In Progress"}})  # FAILS
# update_custom_fields(issue_id, {"State": {"id": "154-2"}})         # FAILS
```

### **🚨 Priority Updates (Very Common)**
```python
# ✅ PROVEN WORKING FORMAT - Use simple strings
update_issue_priority("DEMO-123", "Critical")
update_issue_priority("PROJECT-456", "Major") 
update_issue_priority("TASK-789", "Normal")

# ❌ DON'T USE - Complex objects fail
# update_custom_fields(issue_id, {"Priority": {"name": "Critical"}})  # FAILS
# update_custom_fields(issue_id, {"Priority": {"id": "152-1"}})       # FAILS
```

### **👤 Assignment Updates (Common)**
```python
# ✅ PROVEN WORKING FORMAT - Use login names
update_issue_assignee("DEMO-123", "admin")
update_issue_assignee("PROJECT-456", "john.doe")
update_issue_assignee("TASK-789", "jane.smith")

# ❌ DON'T USE - Complex objects fail
# update_custom_fields(issue_id, {"Assignee": {"login": "admin"}})    # FAILS
```

### **🏷️ Type Updates (Common)**
```python
# ✅ PROVEN WORKING FORMAT - Use simple strings
update_issue_type("DEMO-123", "Bug")
update_issue_type("PROJECT-456", "Feature")
update_issue_type("TASK-789", "Task")

# ❌ DON'T USE - Complex objects fail
# update_custom_fields(issue_id, {"Type": {"name": "Bug"}})          # FAILS
```

### **⏱️ Time Estimation (Common)**
```python
# ✅ PROVEN WORKING FORMAT - Use simple time strings
update_issue_estimation("DEMO-123", "4h")     # 4 hours
update_issue_estimation("PROJECT-456", "2d")  # 2 days
update_issue_estimation("TASK-789", "30m")    # 30 minutes

```

### **⚡ Complete Issue Workflows**
```python
# 🎯 Complete Triage Workflow
update_issue_type("DEMO-123", "Bug")           # Classify as bug

update_issue_state("DEMO-123", "In Progress")  # Start work
add_comment("DEMO-123", "Critical bug triaged and assigned")

# 🚀 Feature Development Workflow  
update_issue_type("PROJ-456", "Feature")       # Classify as feature
update_issue_priority("PROJ-456", "Normal")    # Standard priority
update_issue_assignee("PROJ-456", "jane.doe")  # Assign to developer
update_issue_estimation("PROJ-456", "2d")      # Estimate 2 days
add_comment("PROJ-456", "Feature ready for development")

# ✅ Task Completion Workflow
update_issue_state("TASK-789", "Fixed")        # Mark as fixed
add_comment("TASK-789", "Implementation completed and tested")

# 📊 Quick Updates (Most Common)
update_issue_state("DEMO-123", "In Progress")       # Start work
update_issue_priority("DEMO-123", "Critical")       # Escalate
update_issue_assignee("DEMO-123", "admin")          # Reassign
update_issue_type("DEMO-123", "Bug")                # Reclassify
update_issue_estimation("DEMO-123", "6h")           # Re-estimate
```

### **📝 Other Custom Fields**
```python
# ✅ Working formats for different field types:

# Priority (enum field)
update_custom_fields("DEMO-123", {"Priority": "Critical"})

# Assignee (user field) 
update_custom_fields("DEMO-123", {"Assignee": "admin"})

# Estimation (period field)
update_custom_fields("DEMO-123", {"Estimation": "4h"})

# Type (enum field)
update_custom_fields("DEMO-123", {"Type": "Bug"})

# Multiple fields at once
update_custom_fields("DEMO-123", {
    "Priority": "Critical",
    "Assignee": "admin", 
    "Type": "Bug"
})
```

### **🔍 Finding Issues**
```python
# Search by text
search_issues("bug in login")

# Search by project
get_project_issues("DEMO")

# Get specific issue
get_issue("DEMO-123")
```

### **📋 Creating Issues**
```python
create_issue(
    project_id="DEMO",
    summary="Bug in login system",
    description="Users cannot log in with special characters"
)
```

## Installation

[![Docker Build and Push](https://github.com/tonyzorin/youtrack-mcp/actions/workflows/docker-build.yml/badge.svg)](https://github.com/tonyzorin/youtrack-mcp/actions/workflows/docker-build.yml)

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)
```bash
# 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)
```bash
# 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
```
