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

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

  "method": "tools/call",
  "params": {
    "name": "mysql_drop_foreign_key",
    "arguments": {}

## Why mysql_drop_foreign_key is rated Critical

Dropping a foreign key constraint is a schema modification that cannot be easily undone without knowledge of the original constraint definition. While not deleting data directly, it removes referential integrity protection and alters the database structure irreversibly.

From the tool's own definition: "Tool name contains 'drop' and description states 'Drop a foreign key constraint from a table' — this irreversibly removes a database constraint."

## Use case

AI agents call mysql_drop_foreign_key to permanently remove resources in Mcp Windows, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp Windows:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "mysql_drop_foreign_key"
  ]
}
```
