# clear_values

Empties the VALUES of one or more A1 ranges in a single call — cell contents and formulas are gone (no undo through the API), while formatting, data validation, notes, conditional formats and merges all stay. To also remove formatting use format_cells or raw_request; to delete whole rows/columns (not just their content) use manage_dimensions action=delete.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "clear_values",
    "arguments": {
      "ranges": [],
      "spreadsheet_id": "<spreadsheet_id>"
    }
  }
}
```

## Why clear_values is rated Critical

Irreversibly deletes cell content and formulas with no API-level undo capability.

From the tool's own definition: "Empties VALUES... cell contents and formulas are gone (no undo through the API)"

## Use case

AI agents call clear_values to permanently remove resources in Mcp Google Sheets, 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 Mcp Google Sheets:

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