Parameters from the server's own tool schema.
This tool retrieves publicly available BoardGameGeek user collection data based on specified filters (owned, wishlist, or played status). It has no side effects, does not modify data, execute code, or produce irreversible changes. The only risk is potential privacy concerns if user collection data is sensitive, but the operation itself is purely a read/query function.
From the tool's definition Tool description states 'Get a BGG user's game collection filtered by status' - the verb 'Get' and the filtering operation indicate data retrieval with no modification, deletion, or execution of arbitrary operations.
