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

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

## Why checksum_and_verify_pack is rated Low

This tool retrieves and compares cryptographic hash values to validate artifact integrity. It has no side effects, does not modify data, does not execute arbitrary code, and does not delete or move resources. It falls squarely into the Read category as a data integrity checking operation.

From the tool's own definition: "The tool description states it 'Compute[s] or verify[ies] SHA-256 checksums' for TouchDesigner artifacts. Computing and verifying checksums are read-only operations that inspect data integrity without modifying, deleting, or executing code."

## Use case

AI agents call checksum_and_verify_pack 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": {
    "checksum_and_verify_pack": {}
  }
}
```
