WHAT IT DOES

What import_model does on Aos

AI agents use import_model 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.

RISK

Why import_model is rated Medium

This tool creates and adds new data structures (model import + SOP operator) to a TouchDesigner project, which is reversible and matches the Write category. While it involves external file I/O, the primary action is creating/adding project components rather than destructively modifying or executing arbitrary code.

From the tool's definition Tool description states 'Import a 3D model file (.obj/.fbx/.usd) and render it to a TOP', indicating it creates or modifies visual assets and project state within TouchDesigner by adding a new 3D model asset and associated operator (File In SOP) to the…

RECOMMENDED RULE

The rule that runs import_model 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 import_model, this is the rule to start with:

import_model Rate-limited

import_model 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 import_model call is checked against it from then on.

FAQ

Questions about import_model

What does the import_model tool do? +

Import a 3D model file (.obj/.fbx/.usd) and render it to a TOP: a File In SOP reading. It is categorised as a Write tool in the Aos MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on import_model? +

Register the Aos MCP server in PolicyLayer and add a rule for import_model: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Aos. Nothing to install.

What risk level is import_model? +

import_model is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit import_model? +

Yes. Add a rate_limit block to the import_model rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block import_model completely? +

Set action: deny in the PolicyLayer policy for import_model. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides import_model? +

import_model is provided by the Aos MCP server (@hybridlabor-api/aos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
