Error Handling

The server implements comprehensive error handling:

  • Retry Mechanisms: Automatic retry with exponential backoff

  • Authentication Errors: Clear messages for credential issues

  • API Rate Limiting: Handles rate limits gracefully

  • Network Issues: Robust handling of connection problems

  • Validation: Input validation with helpful error messages

Logging

The server uses Python's logging module with configurable levels:

import logging logging.basicConfig(level=logging.INFO)

Usage Examples

Basic Workflow

  1. Fetch Jira Issues:

# Using MCP tool { "tool": "get_jira_issues", "arguments": { "jql": "project = MYPROJ AND status = 'To Do'" } }

  1. Create Branch for Issue:

# Using MCP tool { "tool": "create_branch_for_issue", "arguments": { "issue_key": "MYPROJ-123", "project_id": 42 } }

  1. Add Progress Comment:

# Using MCP tool { "tool": "comment_on_issue", "arguments": { "issue_key": "MYPROJ-123", "comment": "Development started in branch feature/MYPROJ-123-fix" } }

Integration with AI Agents

This MCP server is designed to work with AI agents and LLMs. Example integration:

# Example AI agent workflow async def handle_new_issue(issue_key, project_id): # 1. Get issue details issues = await mcp_client.call_tool("get_jira_issues", { "jql": f"key = {issue_key}" }) # 2. Create branch result = await mcp_client.call_tool("create_branch_for_issue", { "issue_key": issue_key, "project_id": project_id }) # 3. Add status comment await mcp_client.call_tool("comment_on_issue", { "issue_key": issue_key, "comment": "Automated branch creation completed" })

Security Considerations

  • Environment Variables: Use environment variables for production

  • Token Rotation: Regularly rotate API tokens

  • Network Security: Use HTTPS for all API communications

  • Access Control: Limit token permissions to minimum required

  • Logging: Avoid logging sensitive information

Troubleshooting

Common Issues

Authentication Errors:

  • Verify API tokens are correct and not expired

  • Check that email matches Jira account

  • Ensure GitLab token has required permissions

Connection Issues:

  • Verify base URLs are correct

  • Check network connectivity

  • Confirm firewall settings allow HTTPS traffic

Permission Errors:

  • Ensure Jira user has project access

  • Verify GitLab token has repository permissions

  • Check project visibility settings

Debug Mode

Enable debug logging:

import logging logging.basicConfig(level=logging.DEBUG)
