## Why suggest_fixes is rated Low

This tool retrieves and analyzes validation data to produce recommendations. It has no side effects—it neither modifies TwinCAT files, executes scripts, nor commits changes. The actual fixing is delegated to separate autofix tools. Low severity because misuse would only produce incorrect suggestions, not unintended modifications to production code.

From the tool's own definition: "Tool name 'suggest_fixes' combined with description 'Generate prioritized fix recommendations from validation results' indicates the tool analyzes validation output and produces suggestions without modifying any data."

## Use case

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