RISK

Why send_portal_link is rated Medium

This tool sends an email to a client, which is a write operation that creates a new communication artifact (email message). It does not read-only query data, execute arbitrary code, delete data irreversibly, or commit financial transactions. The email can theoretically be re-sent, filtered, or its effects mitigated, making it reversible rather than destructive.

From the tool's definition Tool name: send_portal_link. Description: 'Send a client portal access link via email. Side effect: sends portal access email to client.' The tool creates/modifies state by initiating an email communication, which is a reversible write operation.
