Implementation Reference

• src/jira_mcp/server.py:132-154 (handler)

  The main handler function for the 'get_issue' MCP tool. Decorated with @mcp.tool, it fetches the JIRA issue by key using the JIRA client and formats it using the format_issue helper.

  @mcp.tool(
      description="获取JIRA问题详情",
  )
  def get_issue(
      issue_key: str,
  ) -> Dict[str, Any]:
      """获取JIRA问题详情.
      
      Args:
          issue_key: JIRA问题键
      
      Returns:
          Dict[str, Any]: 问题详情
      """
      logger.info(f"获取问题: {issue_key}")
      try:
          client = get_jira_client()
          issue = client.issue(issue_key)
          return format_issue(issue)
      except Exception as e:
          logger.error(f"获取问题 {issue_key} 失败: {str(e)}")
          return {"error": str(e)}

• src/jira_mcp/server.py:48-129 (helper)

  Helper function used by get_issue to format the raw JIRA issue object into a structured dictionary with key fields like summary, status, assignee, attachments, etc.
