RISK

Why crm_batch_update_objects is rated Medium

This tool creates or modifies data reversibly—the defining characteristic of Write category. It does not delete or destroy data (Destructive), does not execute arbitrary code (Execute), and does not move money (Financial). The 'batch' aspect and multiplicity of objects affected elevates severity to high, as a single misdirected call could corrupt many records.

From the tool's definition Tool name 'crm_batch_update_objects' and description 'Update multiple CRM objects in a single request' indicate modification of data. The batch operation on 'multiple' objects amplifies the blast radius compared to single-object updates.
