WHAT IT DOES

What wavexis_fill does on Wavexis

AI agents use wavexis_fill 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_fill is rated Medium

wavexis_fill creates or modifies data reversibly—a user can undo the fill action or clear the input field afterward. It does not execute arbitrary code, delete data irreversibly, or move money. While it interacts with web pages via browser automation, the scope of impact is limited to a single input element's value.

From the tool's definition Tool description states: 'Fill an input element with a value (replaces existing content)'. This directly modifies form data by replacing existing content in input elements.

RECOMMENDED RULE

The rule that runs wavexis_fill safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Wavexis, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For wavexis_fill, this is the rule to start with:

wavexis_fill Rate-limited

wavexis_fill stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
