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,
