WHAT IT DOES

What rank_rows does on Mcp Excel

AI agents call rank_rows to retrieve information from Mcp Excel without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why rank_rows needs a policy

The rank_rows tool retrieves and reorganizes data through aggregation and ranking—core read operations. It returns computed rankings and formulas without altering the underlying data. The examples (top customers, bottom products, rankings) all demonstrate data retrieval and analysis. No irreversible changes, code execution, financial impact, or side effects are possible. This is a safe analytical query operation.

From the tool's definition Tool performs ranking and sorting operations on existing data: 'Rank rows by column value', 'Returns ranked rows with rank numbers', 'top/bottom analysis', 'leaderboards', 'percentile ranking'.

POLICY

How to control rank_rows

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Excel, and nothing reaches the server without passing your rules. This is the rule we recommend for rank_rows:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "rank_rows": {}
  }
}

rank_rows is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Excel — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
