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

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

}
```

## Why ebay_clear_tokens is rated Critical

Clearing all OAuth tokens is a destructive action that cannot be automatically undone—it permanently invalidates authentication state and severs API access. While technically recoverable through re-authentication, the immediate effect is irreversible deletion of security credentials. This is more severe than Write (which is reversible modification) and constitutes destruction of critical authentication material.

From the tool's own definition: "Tool name 'ebay_clear_tokens' with description stating it 'Clear[s] all stored OAuth tokens'. This irreversibly removes authentication credentials, preventing subsequent API operations until re-authentication occurs."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call ebay_clear_tokens to permanently remove resources in Ebay, 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 Ebay:

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