# Nanoid Generator MCP

> Nanoid Generator creates unique IDs that are URL-safe, cryptographically random, and short enough for any modern database or web link. Forget long 36-character UUID strings; this MCP generates collision-resistant identifiers in just 21 characters, making your data cleaner and faster to use across every system.

## Description

When you need a unique identifier, length shouldn't be a problem. This MCP lets any agent generate production-grade IDs that are inherently URL-safe. It uses cryptographic randomness to guarantee security while keeping the output much shorter than traditional UUIDs. You can tell your AI client exactly what format you need—whether it’s purely numeric for an order reference or custom characters for internal tokens. The resulting ID is optimized for data integrity, meaning you don't have to worry about encoding headaches when generating millions of records. It makes reliable, short-form identifiers available directly within the Vinkius catalog.

## Tools

### generate_nanoid
Generates a unique URL-safe ID using cryptographic randomness, supporting custom alphabets for specific formats like numeric order codes or tokens.

## Prompt Examples

**Prompt:** 
```
Generate a short, unique ID for a URL shortener like bit.ly.
```

**Response:** 
```
ID: V1StGXR8_Z5j | 12 chars, URL-safe, no encoding needed. Collision-safe for billions of links.
```

**Prompt:** 
```
I need an 8-digit numeric order ID for our e-commerce checkout.
```

**Response:** 
```
ID: 47829163 | Numeric alphabet, 8 digits. Perfect for human-readable order references.
```

**Prompt:** 
```
Create a secure 32-character API key for our partner integration.
```

**Response:** 
```
ID: kB7xZ9pQ2mN5wR8jF3vH6yT1sL4cD0aX | 32 chars, crypto-random. Entropy: 190+ bits.
```

## Capabilities

### Generate standard unique IDs
The tool creates collision-resistant, URL-safe strings perfect for general database keys and API resources.

### Create numeric order references
You can force the output to use a specific alphabet, letting you generate IDs composed only of numbers for human readability.

### Produce secure, custom-alphabet keys
It allows defining any character set, ensuring the generated ID fits your exact business format while maintaining high entropy and security.

## Use Cases

### Building a global URL shortener
The marketing team needs unique links for thousands of campaigns. Instead of using a standard UUID, the agent uses nanoid to generate compact, collision-safe IDs that fit perfectly into `bit.ly/XYZ` format without requiring any complex encoding.

### Creating e-commerce order references
The operations team needs human-readable identifiers for customer support tickets and invoices. They prompt the agent to generate_nanoid with a numeric alphabet, resulting in an ID like '47829163' that is easy for staff to read and communicate.

### Securing temporary API keys
A partner integration needs high-entropy access tokens. The agent uses the tool, specifying a large character set and ensuring the resulting ID has enough bits of entropy for maximum security, avoiding weak or predictable key generation.

### Indexing internal document metadata
The data science team is building a knowledge graph. They use nanoid to generate unique keys for each indexed document chunk, ensuring that the primary index ID doesn't conflict with other system IDs and remains clean.

## Benefits

- Saves space and bandwidth. Instead of 36-character UUIDs cluttering every URL or database row, this MCP produces highly compact identifiers in just 21 characters.
- Guaranteed security. It uses crypto.getRandomValues() to generate IDs, ensuring the randomness is cryptographically strong—it's not just a random string generator.
- Total flexibility with custom alphabets. Need an ID that only contains numbers for human readability? Or maybe letters and hyphens for a specific client format? You define it.

## How It Works

The bottom line is that you get clean, compact IDs instantly, without having to manage complex encoding rules or worry about generating strings that are too long for your infrastructure.

1. Specify the requirements for the unique identifier—for instance, if you need a standard 21-character key or a numeric code.
2. Send the request to your AI client, which executes the `generate_nanoid` tool using the defined constraints (size, alphabet).
3. Receive the final ID: a short, cryptographically secure string ready for immediate use in URLs, database entries, or API payloads.

## Frequently Asked Questions

**Is the nanoid generator secure enough for API keys?**
Yes. The tool uses cryptographic randomness, ensuring high entropy required for production-grade security. You can generate strong keys that are also compact and URL-safe.

**Can I make an ID that is only numbers using nanoid generator?**
Absolutely. When generating_nanoid, you simply pass the numeric alphabet string ('0123456789') to constrain the output characters.

**What's the main difference between this MCP and a standard UUID library?**
The key difference is length. This MCP produces IDs that are significantly shorter than traditional UUIDs, while maintaining the same high level of collision resistance.

**How do I make sure my generated ID doesn't conflict with existing ones?**
Because it uses cryptographic randomness and is highly efficient, the chance of a collision is astronomically low. You don't need to worry about that manually.

**Does nanoid generator support different character sets for IDs?**
Yes, you have full control over the alphabet used by passing a specific string during the `generate_nanoid` call. This is great for internal system codes.
