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

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

## Why validate_operator_chain is rated Low

This tool retrieves and queries validation information about operator chains against documentation and compatibility rules. It has no ability to create, modify, delete, execute code, or affect system state. The read-only nature and explicit statement that it does not create or modify nodes confirm this is a pure Read category tool with minimal risk.

From the tool's own definition: "Tool description explicitly states 'Read-only: validate an ordered TouchDesigner operator chain against embedded operator docs' and 'It does not create or modify TD nodes.' The tool performs validation and analysis without side effects."

## Use case

AI agents call validate_operator_chain to retrieve information from tdmcp — TouchDesigner MCP server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. 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": {
    "validate_operator_chain": {}
  }
}
```
