WHAT IT DOES

What read_parameter_modes does on Aos

AI agents call read_parameter_modes 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.

RISK

Why read_parameter_modes is rated Low

This tool only retrieves and reports information about parameter states in TouchDesigner nodes. It has no side effects — it does not create, modify, delete, or execute any operations. It is used for inspection, serialization, and debugging purposes only.

From the tool's definition Tool name is 'read_parameter_modes' and description explicitly states 'Read-only' and describes reporting/querying parameter modes, values, and expressions without any modification capability.

RECOMMENDED RULE

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

read_parameter_modes Allowed

read_parameter_modes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_parameter_modes": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every read_parameter_modes call is checked against it from then on.

FAQ

Questions about read_parameter_modes

What does the read_parameter_modes tool do? +

Read-only: for each parameter of a node, report its mode (CONSTANT / EXPRESSION / EXPORT / BIND), its evaluated value, and its raw expression / bind-expression / export-source strings. Use this to faithfully serialize a network for round-trip editing, diffing, or debugging — the evaluated value alone hides which parameters are driven by expressions or exports. Set. It is categorised as a Read tool in the Aos MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on read_parameter_modes? +

Register the Aos MCP server in PolicyLayer and add a rule for read_parameter_modes: 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 read_parameter_modes? +

read_parameter_modes is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit read_parameter_modes? +

Yes. Add a rate_limit block to the read_parameter_modes 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 read_parameter_modes completely? +

Set action: deny in the PolicyLayer policy for read_parameter_modes. 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 read_parameter_modes? +

read_parameter_modes 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.
