WHAT IT DOES

What scaffold_vj_deck does on tdmcp — TouchDesigner MCP server

AI agents use scaffold_vj_deck 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 scaffold_vj_deck is rated Medium

This tool creates new UI components, control surfaces, and MIDI bindings within a TouchDesigner project. These are Write-category operations because they modify project state by adding new operators and parameter bindings. While the changes persist in the project, they are not destructive (no deletion or permanent data loss) and do not execute arbitrary code or trigger external financial operations.

From the tool's definition Tool description states it "builds a DJ-style A/B deck mixer (create_decks)", "adds an on-screen fader control surface (create_control_surface)", and "creates a midiinCHOP control surface (create_external_io)".

Attacks that exploit this kind of access

RECOMMENDED RULE

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

scaffold_vj_deck Rate-limited

scaffold_vj_deck 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.

FAQ

Questions about scaffold_vj_deck

What does the scaffold_vj_deck tool do? +

Compose a complete, playable VJ deck UI in one call: it builds a DJ-style A/B deck mixer (create_decks) with a crossfader, adds an on-screen fader control surface (create_control_surface) with crossfade + per-deck gain faders, and creates a midiinCHOP control surface (create_external_io) whose channels are bound to the same crossfader/gain parameters for hands-on MIDI control. Pass deck_a/deck_b source TOP paths (or omit for test sources), and an optional midi_map of channel→control bindings (defaults to ch1c1→crossfader, ch1c2→gain_a, ch1c3→gain_b). This is the deck-scaffold layer on top of the create_decks primitive — it wires the existing deck, surface, and I/O tools into one UI container. 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 scaffold_vj_deck? +

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

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

Can I rate-limit scaffold_vj_deck? +

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

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

scaffold_vj_deck 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.
