What upload_asset does on Businys
AI agents use upload_asset to create or update resources in Businys, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Businys environment.
Why upload_asset is rated Medium
This tool creates new asset records and modifies entities by attaching files to them. It is a Write operation because it persistently modifies the system state (creates asset records, attaches to galleries/guides/lessons/etc.) but is reversible through deletion.
From the tool's definition Tool description states 'Upload a file (image, PDF, video) and attach it to an entity' and 'Returns the asset record with its URL.' The words 'upload' and 'attach' indicate creation and modification of data.
Attacks that exploit this kind of access
The rule that runs upload_asset safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Businys, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For upload_asset, this is the rule to start with:
upload_asset 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 Businys, apply this rule, and every upload_asset call is checked against it from then on.
