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 · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Calendar Converter.

  1. 01

    Get calendar context

    This capability retrieves metadata for a specific year within a chosen calendar system. It helps your agent find era-based details like the Chinese Zodiac or Japanese Imperial Eras.

  2. 02

    Convert to unix

    This capability turns a date from a specific calendar into a Unix timestamp. Use it when you have a local date and need a universal numeric format.

  3. 03

    Expand unix

    This capability takes a single Unix timestamp and breaks it out into multiple calendar systems at once. It is the fastest way to see how one moment in time looks across different cultures.

Real work

What teams actually run

01

Global App Localization

An agent converts user-entered Gregorian dates into local calendars like Hijri or Thai Solar.

02

Historical Research

A researcher asks the agent to find the equivalent Japanese Era for a specific Gregorian year.

03

Data Normalization

A developer uses the capability to turn various cultural dates into a standard Unix format for a database.

04

Cultural Event Planning

An agent identifies the Chinese Zodiac or specific seasonal metadata for a given year.

One connector, every AI

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

You don't need a client to put Calendar Converter 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 Calendar Converter, so you can see the experience inside your AI.

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