WHAT IT DOES

What excel_clear_range does on Sage MCP

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

RISK

Why excel_clear_range is rated Critical

Clearing cell contents is an irreversible destructive action — the data in the specified range is permanently removed. Although formatting is preserved, the actual data cannot be recovered once cleared (no undo mechanism in an API context). This warrants a Destructive classification with high severity given the potential blast radius of wiping large ranges of spreadsheet data.

RECOMMENDED RULE

The rule that runs excel_clear_range safely

excel_clear_range Hidden

excel_clear_range is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
