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

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

## Why mysql_stats_regression is rated Low

This tool retrieves and analyzes existing column data to compute regression statistics. It does not create, modify, delete, or execute code; it only reads data and performs mathematical analysis. The blast radius of misuse is minimal—an agent could waste compute cycles or return inaccurate statistics, but cannot corrupt data or trigger side effects.

From the tool's own definition: "Tool performs 'simple linear regression analysis' between two columns—a statistical computation on data without modifying, deleting, or executing external operations. No DML/DDL operations are indicated."

## Use case

AI agents call mysql_stats_regression to retrieve information from Mysql Mcp 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 Mysql Mcp:

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