WHAT IT DOES

What add_custom_parameters does on tdmcp — TouchDesigner MCP server

AI agents use add_custom_parameters to create or update resources in tdmcp — TouchDesigner MCP server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tdmcp — TouchDesigner MCP server environment.

RISK

Why add_custom_parameters is rated Medium

This is a Write action: it creates or modifies data (custom parameters on a component) in a way that is reversible—parameters can be removed, adjusted, or reconfigured. It does not delete, destroy, or execute arbitrary code; it simply extends the component's parameter interface.

From the tool's definition Tool appends custom-parameter pages (knobs, sliders, toggles, menus, pulses, RGB, XYZ) to a COMP, which modifies the component's interface and functionality in a reversible, structured manner.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_custom_parameters safely

PolicyLayer is an MCP gateway: it sits between your AI agents and tdmcp — TouchDesigner MCP server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_custom_parameters, this is the rule to start with:

add_custom_parameters Rate-limited

add_custom_parameters 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "add_custom_parameters": {
      "limits": [
        {
          "counter": "add_custom_parameters_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect tdmcp — TouchDesigner MCP server, apply this rule, and every add_custom_parameters call is checked against it from then on.

FAQ

Questions about add_custom_parameters

What does the add_custom_parameters tool do? +

Append a custom-parameter page (knobs, sliders, toggles, menus, pulses, RGB, XYZ) to a COMP so a generated network becomes a tunable, reusable component. Point. It is categorised as a Write tool in the tdmcp — TouchDesigner MCP server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_custom_parameters? +

Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for add_custom_parameters: 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 tdmcp — TouchDesigner MCP server. Nothing to install.

What risk level is add_custom_parameters? +

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

Can I rate-limit add_custom_parameters? +

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

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

add_custom_parameters is provided by the tdmcp — TouchDesigner MCP server MCP server (@dpantani/tdmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
