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

```json
{
  "jsonrpc": "2.0",

## Why mysql_show_schemas is rated Low

This tool performs a read-only query operation (SHOW SCHEMAS in MySQL) that retrieves and displays information about available database schemas. There are no side effects, data modifications, deletions, or external operations triggered. The blast radius is minimal since it only exposes structural database metadata without accessing sensitive data contents or enabling modification.

From the tool's own definition: "Tool name 'mysql_show_schemas' and description 'Show all available database schemas' indicate a retrieval operation that lists metadata without modification or deletion."

## Use case

AI agents call mysql_show_schemas to retrieve information from Mcp Windows 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 Mcp Windows:

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