WHAT IT DOES

What amocrm_update_custom_field does on Allmcp

RISK

Why amocrm_update_custom_field is rated Medium

The 'update' verb clearly indicates a write operation that modifies existing data reversibly. While the empty description reduces confidence, the tool name strongly suggests it updates custom fields in an AmoCRM system, which is a data modification action characteristic of the Write category. Severity is medium because updates can corrupt data or cause business logic issues, but are typically reversible.

From the tool's definition Tool name 'amocrm_update_custom_field' indicates modification of data via an 'update' operation. Description is empty, limiting evidence specificity.
