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

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

## Why spreadsheet_clear_cell is rated Critical

Despite the empty description limiting full certainty, the name strongly suggests the tool deletes or wipes cell contents irreversibly. This is more severe than Write (which is reversible) because clearing a cell destroys existing data.

From the tool's own definition: "Tool name 'spreadsheet_clear_cell' indicates irreversible deletion or erasure of cell data. The 'clear' action on a spreadsheet cell removes content without undo capability in most contexts."

## Use case

AI agents call spreadsheet_clear_cell to permanently remove resources in FreeCAD Robust MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FreeCAD Robust MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "spreadsheet_clear_cell"
  ]
}
```
