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

  "jsonrpc": "2.0",

    "name": "check_login",

## Why check_login is rated Low

This tool only reads the current authentication state of the user session. It has no capability to modify data, execute commands, delete information, or commit financial transactions. The blast radius of misuse is minimal — an attacker could only learn whether a user is logged in, which poses no direct harm. It is straightforward read-access behavior.

From the tool's own definition: "The tool 'check_login' performs a query operation that retrieves login status without modifying any data or triggering side effects. The description explicitly states it 'Check[s] if the user is currently logged into Reddit' — a pure status inspection."

## Use case

AI agents call check_login to retrieve information from Reddit Skills 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 Reddit Skills:

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