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.

Curated set · 1 capability

We ship only the actions that matter.

Capability set01 / 01

01

1 capability in this set.

Part of 1 available through Node.js Crypto.

  1. 01

    Generate random string

    This capability generates cryptographically secure random strings using Node.js crypto.randomBytes(). You can choose from hex, alphanumeric, base64, url_safe, numeric, or distinguishable character sets.

Real work

What teams actually run

01

API Key Generation

Your agent creates high-entropy hex strings to serve as unique identifiers for service authentication.

02

User Invite Codes

The AI generates short, distinguishable codes that are easy for customers to type without errors.

03

Session Management

Generate long, URL-safe tokens to manage user sessions in web applications.

04

Database Salts

Create secure, random strings to use as salts for hashing sensitive data.

Automate a task

Put Node.js Crypto 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

Node.js Crypto 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 Node.js Crypto 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.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 1 capability arrives ready to run.

Preview access · not provider authentication

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

It does not authenticate your account with Node.js Crypto. 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 Node.js Crypto owners hand off.

Developers and security engineers who need to move beyond predictable AI-generated strings.

  • 01

    Backend Developers

    Hand off the task of generating secure database keys or session tokens to the AI.

  • 02

    DevOps Engineers

    Use the MCP to create secure, unique identifiers for infrastructure components.

  • 03

    Security Researchers

    Request strings with specific entropy requirements for testing and auditing.

FAQ

Questions Node.js Crypto owners ask.

  • 01

    Is this more secure than asking an AI to make a random string?

    Yes. LLMs generate strings based on probability, which is predictable. This MCP uses Node.js crypto.randomBytes() to pull true randomness from the operating system.

  • 02

    What character sets are available?

    You can choose from hex, alphanumeric, base64, url_safe, numeric, and a distinguishable set that avoids confusing characters like O and 0.

  • 03

    Can I use this with Claude or Cursor?

    Yes. This MCP is compatible with any MCP-compliant client including Claude, Cursor, and Windsurf.

  • 04

    How do I know how secure the string is?

    The capability returns an entropy report alongside the generated string, telling you exactly how many bits of entropy were used.

  • 05

    What is a distinguishable charset?

    It is a specific character set designed to prevent human error by excluding visually similar characters like I, l, and 1.

  • 06

    Is this truly cryptographically secure?

    Yes. It uses Node.js crypto.randomBytes() which draws from the OS CSPRNG (Cryptographically Secure Pseudo-Random Number Generator). This is the same source used by OpenSSL and TLS.

  • 07

    What is the 'distinguishable' charset?

    It uses only characters that cannot be confused visually: CDEHKMPRTUWXY012458. This avoids pairs like O/0, I/l/1 that cause errors when users type codes manually.

  • 08

    What is the maximum string length?

    1024 characters. This is more than enough for any API key, session token, or invite code. The entropy bits are reported so you can verify the security level.
