# Nanoid Generator MCP for AI Agents AI Agent Connect > Nanoid Generator MCP. It creates unique, URL-safe IDs that are faster and smaller than standard UUIDs. It uses cryptographic randomness so you can generate production-ready keys for URLs, databases, and APIs without worrying about collisions. It's the same tech used by Supabase and Vite. ## Overview - **Category:** loved-by-devs - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_TVEu5996CnXLhJGBtfRzu3THPRhky1AzU06JvAsr/ai-agent-connect - **Tags:** unique-id, cryptography, url-safe, randomness, data-integrity, uuid-alternative ## Description Nanoid Generator lets you create unique, URL-safe IDs that are faster and smaller than standard UUIDs. You're building an app and need a way to identify records without making your URLs look like a mess of long, ugly strings. Standard UUIDs are clunky and often require extra encoding to stay readable in a browser or a shared link. This Connector lets your AI client handle the heavy lifting of ID generation by pulling in the Nanoid library. Instead of the AI guessing what a random string should look like, it uses a proven, cryptographically secure method to create IDs that are actually usable in production. Whether you need a short string for a URL shortener, a numeric-only ID for an order number, or a high-entropy key for a private API, you just tell your agent what you need. It handles the math and the character sets while you focus on the actual logic. It's a reliable way to ensure your data stays organized and your links stay clean. You can find this and thousands of other tools in the Vinkius catalog to keep your development workflow moving without friction. By offloading this to the Connector, you eliminate the risk of collisions that come from poorly implemented random functions. It's about getting production-ready results that work as well in your database as they do in your frontend. ## Tools ### generate_nanoid Generates unique, URL-safe IDs using the nanoid library. You can specify custom alphabets or lengths to fit specific use cases like order numbers or API keys. ## Prompt Examples **Prompt:** ``` I need a short, unique ID for a URL shortener. ``` **Response:** ``` ID: **V1StGXR8_Z5j** * **Length:** 12 characters * **Format:** URL-safe * **Encoding:** None needed * **Safety:** Collision-safe for billions of links. ``` **Prompt:** ``` I need an 8-digit numeric order ID for our checkout. ``` **Response:** ``` ID: **47829163** * **Alphabet:** Numeric only * **Length:** 8 digits * **Use Case:** Perfect for human-readable order references and invoices. ``` **Prompt:** ``` Create a secure 32-character API key for a partner integration. ``` **Response:** ``` ID: **kB7xZ9pQ2mN5wR8jF3vH6yT1sL4cD0aX** * **Length:** 32 characters * **Entropy:** 190+ bits * **Security:** Cryptographically random ``` ## Capabilities ### Create short URL-safe IDs Generate compact strings that don't require percent-encoding in your links. ### Generate numeric-only order IDs Produce IDs using only numbers for human-readable references like invoices. ### Produce high-entropy API keys Create secure, long strings for authentication with high cryptographic entropy. ### Customize ID character sets Define specific alphabets to match your project's naming conventions. ### Ensure cryptographic randomness Use the system's secure random values to prevent ID predictability. ## Use Cases ### Building a URL shortener An engineer asks their agent to create a 12-character unique ID for a new bit.ly style link. The agent uses generate_nanoid to provide a collision-safe string. ### Generating e-commerce order IDs A developer needs 8-digit numeric IDs for a checkout system. The agent calls generate_nanoid with a numeric alphabet to create human-readable references. ### Creating secure partner API keys A security lead asks the agent to create a 32-character secure key for a partner. The agent produces a high-entropy string using cryptographic randomness. ### Populating a database with unique IDs A dev needs to seed a database with unique identifiers. The agent calls generate_nanoid to provide a batch of 21-character, URL-safe strings. ## Benefits - Cleaner URLs: Use 21-character IDs instead of 36-character UUIDs to keep your links short and readable for users. - Custom Alphabets: Use generate_nanoid to create IDs that only use numbers or specific letters for human-readable references. - Cryptographic Security: Every ID produced by this Connector uses crypto.getRandomValues() to ensure high entropy for sensitive keys. - Faster Performance: Generate IDs 2x faster than standard UUID methods, which matters when scaling your database writes. - No Encoding Headaches: IDs are URL-safe by default, so you don't have to worry about percent-encoding in your frontend. ## How It Works The bottom line is you get reliable, collision-resistant IDs without the overhead of UUIDs. 1. Tell your agent what kind of ID you need, like a specific length or a character set. 2. The AI calls generate_nanoid to create the ID based on your requirements. 3. You get a unique, URL-safe string ready to use in your code or database. ## Frequently Asked Questions **What is the Nanoid Generator MCP for?** It helps your AI agent create unique, compact identifiers for things like database records, URLs, and API keys. It's designed to be a better, faster alternative to standard UUIDs. **Is Nanoid Generator MCP safer than just asking an AI for a random string?** Yes. While an AI might hallucinate a string, this Connector uses actual cryptographic randomness. This ensures your IDs and keys are unpredictable and secure for production use. **Can I make the IDs from Nanoid Generator MCP only use numbers?** Yes, you can. You can tell your agent to use a numeric alphabet, which is perfect for creating human-readable order numbers or tracking codes. **Why would I use Nanoid Generator MCP instead of UUIDs?** UUIDs are 36 characters long and often require extra encoding. Nanoid IDs are 21 characters by default, URL-safe, and much easier to handle in URLs and database rows. **Does Nanoid Generator MCP work for creating API keys?** It works great for API keys. It can generate high-entropy strings that are cryptographically secure, making them suitable for partner integrations and internal security. **How long are the IDs from Nanoid Generator MCP?** The default length is 21 characters, which provides a very low collision probability. However, you can ask your agent to generate IDs of different lengths depending on your needs. **Why should I use nanoid instead of UUID?** Nanoid is 40% shorter (21 vs 36 chars), 2x faster, URL-safe without encoding, and has equivalent collision resistance. UUID still wins for enterprise systems that mandate RFC 9562 compliance. **Can I generate IDs with only numbers for order codes?** Yes. Set alphabet to '0123456789' and size to 8 for an 8-digit numeric order code like '47829163'. Works with any character set you define. **Is it safe to use as a secret token or API key?** Yes. Nanoid uses crypto.getRandomValues() — the same cryptographic PRNG used for TLS keys and encryption. Increase the size to 32+ characters for high-security tokens.
