What version_library_asset does on Aos
AI agents use version_library_asset to create or update resources in Aos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aos environment.
Why version_library_asset is rated Medium
This tool creates or modifies versioning metadata for vault assets (recipes/components) in TouchDesigner. It is reversible (version bumps can be adjusted or undone), and affects only metadata/documentation rather than core asset functionality. It does not delete data (Destructive), execute arbitrary code (Execute), or move money (Financial). It is a write operation that updates version information.
From the tool's definition Tool description states 'Apply a SemVer patch/minor/major bump to a vault recipe or component note, recording the change' — this modifies version metadata and change records for existing assets.
Attacks that exploit this kind of access
The rule that runs version_library_asset safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For version_library_asset, this is the rule to start with:
version_library_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 Aos, apply this rule, and every version_library_asset call is checked against it from then on.
