WHAT IT DOES

What merge_cells does on Excel MCP Server with Supabase Storage

RISK

Why merge_cells is rated Medium

Merging cells modifies the spreadsheet layout and structure but does not delete data or trigger external operations. The action is reversible (cells can be unmerged), making it a Write operation rather than Destructive. The severity is low because the impact is limited to formatting/structure within a single spreadsheet with no data loss or side effects on external systems.

From the tool's definition Tool name 'merge_cells' and description '合并单元格' (merge cells in Chinese) indicate a cell formatting operation that modifies spreadsheet structure. This is a reversible data modification operation typical of Excel manipulation tools.
