Implementation Reference

• src/zabbix_mcp_server.py:193-220 (handler)

  The host_update MCP tool handler function that updates an existing host in Zabbix using the Zabbix API client. It validates read-only mode, prepares parameters, calls the API, and formats the response.

  @mcp.tool()
  def host_update(hostid: str, host: Optional[str] = None, 
                  name: Optional[str] = None, status: Optional[int] = None) -> str:
      """Update an existing host in Zabbix.
