Implementation Reference

• src/zabbix_mcp_server.py:542-574 (handler)

  The handler function for the 'trigger_update' tool, decorated with @mcp.tool() which also serves as registration. It updates a Zabbix trigger using the ZabbixAPI client, validating read-only mode first.

  @mcp.tool()

                     expression: Optional[str] = None, priority: Optional[int] = None,
                     status: Optional[int] = None) -> str:
