Clear data from a specific range in a spreadsheet
AI agents call clear-range to permanently remove resources in Google Sheets MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing a range deletes data without the ability to restore it unless the user has enabled version history or backups outside the tool's control. This is an irreversible data loss operation, making it Destructive rather than Write. While not as broad as dropping an entire table, clearing ranges can affect critical business data.
From the tool's definition Tool name is 'clear-range' and description states it will 'Clear data from a specific range in a spreadsheet.' The verb 'clear' in the context of spreadsheet operations irreversibly removes data.
Attacks that exploit this kind of access
Clear data from a specific range in a spreadsheet. It is categorised as a Destructive tool in the Google Sheets MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Google Sheets MCP Server MCP server in PolicyLayer and add a rule for clear-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 Google Sheets MCP Server. Nothing to install.
clear-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-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-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-range is provided by the Google Sheets MCP Server MCP server (prajapdh/sheets-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
