Parameters from the server's own tool schema.
This tool performs a data retrieval operation against a public LEGO set database (Brickset). It has no capability to modify data, execute arbitrary code, move funds, or delete information. The blast radius of misuse is minimal — an agent could only retrieve excessive amounts of LEGO set information, which poses negligible security risk.
