# login

Make sure there is a Moodle session. If there is one, returns the logged-in user at once. Otherwise opens a browser window at the site's login page and waits until the person logs in there themselves (the server never sees their password), then returns the user. Call it when another tool reports a missing or expired session.

## Parameters

| Parameter | Type | Required | Description |

Parameters from the server's own tool schema.

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

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

## Why login is rated Medium

An AI agent can call login faster than any human can review: one bad instruction and it creates or modifies resources in Moodle by the hundred, each call as confident as the last.

## Use case

AI agents use login to create or update resources in Moodle, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Moodle environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "login": {
      "limits": [
        {
          "counter": "login_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
