Why ai_provider_status needs a policy

This tool retrieves status information about AI providers (similar to a health check or status endpoint). It has no side effects, does not create, modify, or delete data, and does not execute code or trigger external operations. It is a pure read operation that queries the current state of available AI providers.

From the tool's definition Tool name 'ai_provider_status' and description 'Check status of available AI providers' indicate a query/retrieval operation that returns status information about AI services without modifying, executing, or affecting any data or external systems.

POLICY

How to control ai_provider_status

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 ai_provider_status:

policy.json

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

ai_provider_status 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.
