Why smart_data_analysis needs a policy

This tool retrieves and analyzes data to generate insights and recommendations. It does not create, modify, delete, or execute operations with external side effects. The severity is low because misuse would only result in incorrect analysis suggestions without affecting data integrity or system state.

From the tool's definition Tool is described as 'AI-powered analysis suggestions for your data' with no capability to modify, delete, or execute code. The verb 'suggestions' and context of 'analysis' indicate data retrieval and interpretation only.

POLICY

How to control smart_data_analysis

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

policy.json

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

smart_data_analysis 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 Excel MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
