## Why list_worksheets is rated Low

This tool retrieves or lists worksheet metadata from an Excel file without modifying data or executing arbitrary code. It has no side effects and fits squarely within the Read category. Severity is low because misuse by an AI agent would only expose structure information about a workbook, not enable destructive or financial harm.

From the tool's own definition: "Tool name 'list_worksheets' indicates a retrieval operation that queries the structure of an Excel workbook."

## Use case

AI agents call list_worksheets to retrieve information from Excel 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 Excel MCP Server:

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