WHAT IT DOES

What wavexis_sessionstorage_set does on Wavexis

AI agents use wavexis_sessionstorage_set to create or update resources in Wavexis, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Wavexis environment.

RISK

Why wavexis_sessionstorage_set is rated Medium

This tool writes data to the browser's sessionStorage (analogous to a dictionary/map operation). It creates or overwrites a key-value pair, which is reversible (the value can be changed or deleted via a separate operation). This does not involve deletion, code execution, or financial operations.

From the tool's definition Tool name contains 'set' and description states 'Set a sessionStorage key/value pair' — this directly modifies browser storage by writing/creating data.
