Clear all values in a range. Range format: 'Sheet1!A1:D10'.
AI agents call clear_spreadsheet_range to permanently remove resources in Gg — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing all values in a spreadsheet range is a destructive operation: the data is wiped and cannot be recovered through the tool itself. The range format (e.g., 'Sheet1!A1:D10') could cover arbitrarily large portions of a spreadsheet, giving this tool a high blast radius if misused by an AI agent.
From the tool's definition 'Clear all values in a range' — irreversibly removes data from a spreadsheet range

Attacks that exploit this kind of access
Clear all values in a range. Range format: 'Sheet1!A1:D10'. It is categorised as a Destructive tool in the Gg MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Gg MCP server in PolicyLayer and add a rule for clear_spreadsheet_range: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gg. Nothing to install.
clear_spreadsheet_range is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clear_spreadsheet_range rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for clear_spreadsheet_range. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
clear_spreadsheet_range is provided by the Gg MCP server (tannht/google-cloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
