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 Numeral.js.

  1. 01

    Format numeral

    This capability converts raw numbers into specific display strings using Numeral.js patterns. You pass a number and a pattern like '$0,0.00' for currency or '0%' for percentages to get a perfectly formatted result.

Real work

What teams actually run

01

Automated Financial Reporting

An agent processes a CSV of transactions and uses this MCP to write a summary with correctly formatted dollar amounts.

02

System Monitoring Dashboards

Your AI client takes raw byte counts from a server log and converts them into readable MB or GB formats.

03

Statistical Summaries

An agent calculates growth rates and uses the capability to present them as clean percentages.

04

Data Visualization Prep

You use this to prepare raw numeric data for display in a text-based UI or chat interface.

Automate a task

Put Numeral.js 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

Numeral.js 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 Numeral.js 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 Numeral.js, so you can see the experience inside your AI.

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