Implementation Reference

• src/zabbix_mcp_server.py:595-630 (handler)

  The handler function decorated with @mcp.tool() that implements the template_get MCP tool. It retrieves templates from the Zabbix API using client.template.get with optional filters and returns formatted JSON.
  def template_get(templateids: Optional[List[str]] = None, groupids: Optional[List[str]] = None, hostids: Optional[List[str]] = None, output: Union[str, List[str]] = "extend", search: Optional[Dict[str, str]] = None, filter: Optional[Dict[str, Any]] = None) -> str: """Get templates from Zabbix with optional filtering.
