# generate_random

utilpeek: Generate cryptographically strong random numbers, bytes, UUIDs, dice rolls, picks and shuffles. For UUIDs and ULIDs use generate_ids. Returns values from the OS CSPRNG (Python secrets): integers (uniform, inclusive range), floats in [min, max), 1-1,024 random bytes (hex or base64), UUID v4, dice rolls such as 3d6 or 2d10+3 with the total, picks from a list or a shuffle. Input: optional kind, min and max, count, length and encoding, dice, items and unique; an empty body gives one integer 0-100. Parameters that do not fit the kind, count over 1,000 or more than 1,000 items are a 422 before any payment (not charged). Nothing is stored or logged. Generate secret keys locally. Typically under 0.1 s. Price: USD 0.001. Free: 10 utilpeek calls per IP per UTC day.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `max` | object | no | int: highest value, inclusive (default 100). float: upper bound, exclusive (default 1); max must exceed min. |
| `min` | object | no | int: lowest value, inclusive (default 0). float: lowest, inclusive (default 0). |
| `dice` | object | no | dice: an expression such as 3d6, d20 or 2d10+3 (1-100 dice of 2-1000 sides, optional +/- modifier; default 1d6). |
| `kind` | string | no | int (default), float, bytes, uuid (v4), dice, pick or shuffle. |
| `count` | integer | no | How many values (1-1000, default 1): int, float, uuid, pick. |
| `items` | object | no | pick / shuffle: a comma-separated list (at most 1,000 items of 200 characters; blanks are dropped). |
| `length` | integer | no | bytes: how many random bytes (1-1024, default 16). |
| `unique` | boolean | no | pick: draw without replacement (count at most the number of items). |
| `encoding` | string | no | bytes: hex (default) or base64. |

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

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

## Why generate_random is rated Medium

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

## Use case

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

## Recommended policy (PolicyLayer)

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

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
