WHAT IT DOES

What set_parameters_batch does on tdmcp — TouchDesigner MCP server

AI agents use set_parameters_batch 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 set_parameters_batch is rated Medium

This tool creates or modifies data (TouchDesigner node parameters) reversibly. While the batch nature and lack of rollback could amplify blast radius if an agent misconfigures many nodes at once, the operations are not destructive (parameters can be reset/undone) or executable (no code/shell execution).

From the tool's definition Tool performs 'Update parameters on multiple nodes' — a direct modification operation. The description explicitly states it modifies state ('update parameters') on potentially many targets ('multiple nodes').

Attacks that exploit this kind of access

RECOMMENDED RULE

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

set_parameters_batch Rate-limited

set_parameters_batch 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 set_parameters_batch call is checked against it from then on.

FAQ

Questions about set_parameters_batch

What does the set_parameters_batch tool do? +

Update parameters on multiple nodes in a single batch request. Each update reports its own success; a failure does not roll back the others. 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 set_parameters_batch? +

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

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

Can I rate-limit set_parameters_batch? +

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

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

set_parameters_batch 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.
