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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "vault_login",
    "arguments": {
      "profile": "<profile>"
    }
  }
}
```

## Why vault_login is rated Low

The name suggests authentication/login to a vault system, which could involve reading credentials, writing session tokens, or executing an auth flow. However, with no description available, it's unclear whether it reads, writes, or executes. Given the 'vault' context (likely credential storage) and 'login' action, it most plausibly initiates an authentication session (Write-level at most), but confidence is low.

From the tool's own definition: "Tool name is 'vault_login'; description is empty or uninformative."

Risk signals: Accepts URL/endpoint input (url)

## Use case

AI agents call vault_login as a supporting operation in Looking Glass workflows.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "vault_login": {
      "limits": [
        {
          "counter": "vault_login_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
```
