## Why github_login is rated Low

This tool performs authentication/authorization setup, not data retrieval, modification, execution, destruction, or financial operations. It initiates an OAuth device flow and completes token acquisition. While it grants access to GitHub resources, the tool itself does not read, write, execute, or destroy anything — it is purely a credential/session establishment mechanism.

From the tool's own definition: "Authenticate via GitHub OAuth device flow. First call returns a code + URL to open; run it again after authorizing to finish."

## Use case

AI agents call github_login as a supporting operation in GitHub workflows.

## Recommended policy (PolicyLayer)

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

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