What wavexis_fill_form does on Wavexis
AI agents use wavexis_fill_form 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.
Why wavexis_fill_form is rated Medium
Filling form fields is a Write operation: it creates or modifies data on a web page. The action is reversible (form can be cleared/reset). However, severity is high because an LLM could misuse this to submit sensitive credentials, personal information, or financial details into unintended forms, with limited visibility into what those forms do.
From the tool's definition Tool description states 'Fill multiple form fields in one call' — this modifies form data, a reversible write operation on web page state.
Attacks that exploit this kind of access
The rule that runs wavexis_fill_form 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_form, this is the rule to start with:
wavexis_fill_form 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Wavexis, apply this rule, and every wavexis_fill_form call is checked against it from then on.
