WHAT IT DOES

What create_macro does on tdmcp — TouchDesigner MCP server

AI agents use create_macro 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 create_macro is rated Medium

This tool creates and modifies data (custom parameters and expression bindings) within a TouchDesigner project, which is reversible—macros can be deleted or modified later. It does not execute arbitrary code, delete data, move money, or trigger external operations. The changes are confined to parameter setup and expression binding, making it Write-category.

From the tool's definition Tool creates a macro knob (a custom parameter) and adds it to a COMP, establishing live expression bindings to other parameters.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_macro Rate-limited

create_macro 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 tdmcp — TouchDesigner MCP server, apply this rule, and every create_macro call is checked against it from then on.

FAQ

Questions about create_macro

What does the create_macro tool do? +

Add one macro knob (a 0–1 custom parameter) to a COMP that drives many parameters at once, each remapped into its own [min,max] range with an optional response curve — a one-to-many control for sweeping a whole look from a single fader. Targets are bound by expression so they track the macro live. 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 create_macro? +

Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for create_macro: 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 create_macro? +

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

Can I rate-limit create_macro? +

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

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

create_macro 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.
