WHAT IT DOES

What wavexis_localstorage_set does on Wavexis

AI agents use wavexis_localstorage_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_localstorage_set is rated Medium

This tool creates or modifies localStorage entries, which are browser-persisted data that can affect application state and user settings. While reversible (values can be overwritten or cleared), it modifies client-side state that may influence application behavior, session management, or user preferences.

From the tool's definition Tool name explicitly states 'set' and description confirms it 'Set[s] a localStorage key/value pair', indicating creation/modification of browser storage data.
