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

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

## Why validate_batch is rated Low

The naming pattern (validate_batch) combined with sibling tools all performing query/check operations strongly suggests this tool retrieves validation results or checks TwinCAT files without modifying them. The word 'batch' indicates it processes multiple files, but batch processing for validation is inherently a Read operation.

From the tool's own definition: "Tool name 'validate_batch' and server context indicate validation/checking functionality. Sibling tools include 'check_specific', 'get_validation_summary', 'lint_oop_policy', and 'get_context_pack' which are clearly Read operations."

## Use case

AI agents call validate_batch to retrieve information from TwinCAT Validator 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 TwinCAT Validator MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "validate_batch": {}
  }
}
```
