WHAT IT DOES

RISK

Why set_group_add_request is rated Medium

This tool writes/modifies group membership data by processing join requests, which is a reversible operation (users can leave or be removed later). It does not delete data permanently, execute arbitrary code, or move money, so it falls under Write category.

From the tool's definition Tool name 'set_group_add_request' and description 'Handle group join request' indicate the tool modifies group membership state by accepting or rejecting join requests, creating reversible changes to group composition.
