RISK

It is a passive data retrieval operation consistent with other 'get_*' tools on this Yahoo Finance server (get_crypto_quotes, get_analyst_estimates, etc.).

From the tool's definition Tool name 'get_calendar_data' and description 'retrieves calendar data according to event type' indicate data retrieval with no modification or execution. The verb 'get' and 'retrieves' are characteristic of Read operations.
