RISK

Why upload_message_attachments is rated Medium

This tool creates or modifies message data by attaching files, making it a Write operation. Severity is medium because uploaded attachments could contain malicious files or be used to spam/harass users, but the operation is reversible (attachments can typically be removed). Confidence is 0.85 because the description is minimal but the intent is clear from the name and verb.

From the tool's definition Tool name is 'upload_message_attachments' with description 'Upload file attachments for use in messages' — the verb 'upload' indicates creation/addition of file data to a message system.
