- Server: tdmcp — TouchDesigner MCP server (`@dpantani/tdmcp`) — https://policylayer.com/tools/io-github-pantani-tdmcp.md
- Install: `npx -y @dpantani/tdmcp`
- Homepage: https://github.com/Pantani/tdmcp

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "variant_pack",
    "arguments": {}
  }
}
```

## Why variant_pack is rated Medium

The tool creates multiple perturbed variants (generative/transformative operation) and explicitly writes them to persistent storage (Obsidian vault). This is a Write operation—it modifies the state of the vault by adding new JSON data structures. While it has some Read characteristics (probing the target component), the primary intent and effect is to create and persist new data.

From the tool's own definition: "Tool generates and writes 'the whole pack to the Obsidian vault as...JSON' and 'Probes the target COMP', indicating data creation and modification operations that persist to storage."

## Use case

AI agents use variant_pack 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches tdmcp — TouchDesigner MCP server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "variant_pack": {
      "limits": [
        {
          "counter": "variant_pack_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
