What compact_graph_digest does on Aos
AI agents call compact_graph_digest to retrieve information from Aos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why compact_graph_digest is rated Low
This tool only retrieves and summarizes information from a TouchDesigner project subtree without modifying, executing, or deleting anything. It is a query/analysis operation with no side effects, fitting the Read category. Low severity because reading project structure poses minimal risk to the system.
From the tool's definition Tool name includes 'Read-only' prefix in description; action is 'compress a TD subtree into a structured digest' with no modification or deletion of data.
Attacks that exploit this kind of access
The rule that runs compact_graph_digest 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 compact_graph_digest, this is the rule to start with:
compact_graph_digest is read-only, so it stays allowed. 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 compact_graph_digest call is checked against it from then on.
