Interacting with the Server

The YouTrack MCP server exposes tools following the Model Context Protocol. LLM applications can discover and use these tools to interact with YouTrack.

Example: Creating an Issue

  "tool": "create_issue",
  "params": {
    "projectId": "PROJECT-1",
    "summary": "Implement new feature",
    "description": "We need to implement the new feature as described in the specs.",
    "type": "Task",
    "priority": "Normal"
  }
}

Example: Searching Issues

{
  "tool": "search_issues",
  "params": {
    "query": "project: PROJECT-1 #bug state: Open",
    "limit": 10
  }
}

Example: Starting Work on an Issue

{
  "tool": "start_working_on_issue",
  "params": {
    "issueId": "PROJECT-1-123",
    "comment": "Starting implementation of this feature",
    "estimatedTime": "2d"
  }
}

# Run linting
npm run lint

# Run type checking
npm run type-check

# Build the project
npm run build

Project Structure

Troubleshooting

Common Issues

1. Authentication errors: Verify your YouTrack token has the necessary permissions and hasn't expired.

2. Project not found: Ensure the project ID exists and is accessible to your account.

3. API rate limiting: YouTrack may impose rate limits. Consider implementing retry logic for critical operations.

4. State transition errors: Some state transitions may be prohibited by your YouTrack workflow configuration.

Logs

Logs are stored in the logs directory:

• combined.log - All log entries

• error.log - Error-level logs only

Set the LOG_LEVEL environment variable to control logging verbosity (error, warn, info, debug).
