## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "analyze_group_stats",
    "arguments": {}
  }
}
```

## Why analyze_group_stats is rated Low

Based on the naming convention matching other analytical tools (analyze_*) and the server's stated capabilities, this tool most likely performs read-only statistical analysis of grouped data within Excel workbooks. No write or destructive operations are indicated by the name or context. Confidence is slightly reduced due to missing description, but the pattern matching with sibling tools is strong evidence.

From the tool's own definition: "Tool name 'analyze_group_stats' with no description provided. Sibling tools on the server are all read-only analytical functions (analyze_correlations, analyze_data, analyze_missing_values, list_columns, list_worksheets, get_random_sample)."

## Use case

AI agents call analyze_group_stats to retrieve information from Excel MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Excel MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "analyze_group_stats": {}
  }
}
```
