Why shouldn't I just let my AI generate a UUID?

AI models often hallucinate the internal structure of a UUID. They might get the version or variant bits wrong, which results in invalid identifiers that fail database validation.

What is the difference between v4 and v7 UUIDs?

v4 is completely random and good for general use. v7 is time-ordered, meaning it includes a timestamp that makes it much better for database indexing and sorting.

How do I get the same UUID for the same input?

You should use the v5 version. It is deterministic, meaning the same name and namespace will always produce the same UUID.

Is this compliant with industry standards?

Yes, this MCP follows the RFC 9562 standard, which is used by major financial and healthcare institutions.

Which database types work best with these UUIDs?

The v7 UUIDs are specifically designed to be efficient for B-tree indexes in databases like PostgreSQL and DynamoDB.

Which version should I use for database primary keys?

v7. It embeds a Unix timestamp in the first 48 bits, making UUIDs naturally sortable by creation time. This dramatically improves B-tree index performance compared to random v4 UUIDs.

When would I use v5 instead of v4?

When you need the same input to always produce the same UUID. Example: generating a consistent UUID for 'api.example.com' across multiple services. all will produce the same ID without coordination.

Can the AI generate valid UUIDs on its own?

No. AI-generated UUIDs look valid but have incorrect version bits, wrong variant fields, and predictable entropy. This engine generates cryptographically valid UUIDs that pass RFC 9562 validation.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

1 capability in this set.

Part of 1 available through uuid.

01
Generate uuid
This capability produces RFC 9562 compliant UUIDs in v4, v5, or v7 formats. You can choose between random, deterministic, or time-ordered identifiers depending on your specific data needs.

Real work

What teams actually run

Database Primary Keys

Use v7 UUIDs to create sortable keys that work efficiently with PostgreSQL or DynamoDB.

Microservice Consistency

Use v5 UUIDs to ensure different services generate the exact same ID for a specific domain or name.

User Account Creation

Use v4 UUIDs to generate high-entropy, random identifiers for new user profiles.

Data Integrity Audits

Use the capability to generate valid IDs that pass strict schema validation in regulated industries.

Automate a task

Put uuid to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

uuid works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put uuid to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of uuid, so you can see the experience inside your AI.

It does not authenticate your account with uuid. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work uuid owners hand off.

This MCP is built for engineers who need to ensure their AI-driven workflows produce data that won't break production databases.

01
Backend Engineers
They use the agent to generate primary keys that won't cause index fragmentation.
02
Database Administrators
They rely on the agent to produce time-ordered identifiers for better write performance.
03
DevOps Engineers
They use deterministic IDs to maintain consistency across distributed microservices.
