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

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

## Why mysql_optimize_table is rated High

OPTIMIZE TABLE is an in-place table reorganization operation. It is not a simple read, write, or delete — it executes a maintenance operation that rebuilds the table and indexes, potentially locking the table during the process. While it doesn't destroy data intentionally, misuse could cause prolonged table locks affecting production availability.

From the tool's own definition: "'Optimize a table to reclaim unused space and defragment' — this triggers a database engine operation (OPTIMIZE TABLE) that reorganizes physical storage and rebuilds indexes"

## Use case

AI agents invoke mysql_optimize_table to trigger actions in Mysql. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mysql:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "mysql_optimize_table": {
      "limits": [
        {
          "counter": "mysql_optimize_table_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
