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 Cron Parser.

  1. 01

    Calculate next cron dates

    This capability calculates the exact mathematical timestamps for the next scheduled runs of a cron expression.

Real work

What teams actually run

01

Cron Debugging

Verify if a specific cron expression actually does what you think it does.

02

Automation Planning

Get a list of future run times to coordinate other system tasks.

03

Syntax Auditing

Check user-provided cron strings for structural errors before deploying them.

04

Schedule Documentation

Translate cryptic cron strings into readable human schedules for team updates.

Automate a task

Put Cron Parser 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

Cron Parser 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 Cron Parser 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.

Connect your client

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 Cron Parser, so you can see the experience inside your AI.

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

FAQ

Questions Cron Parser owners ask.

  • 01

    How does this MCP prevent AI hallucinations?

    It replaces the AI's internal math with a deterministic JavaScript library that calculates dates programmatically.

  • 02

    Which AI clients can use this MCP?

    Any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code can use this capability.

  • 03

    Can it validate if a cron string is correct?

    Yes, the capability can check if a cron expression is structurally sound.

  • 04

    Does it handle complex schedules?

    Yes, it uses the cron-parser library to handle complex expressions and specific time constraints.

  • 05

    Do I need to host the MCP myself?

    No, Vinkius hosts and manages the MCP for you, so it is ready to use immediately after connection.

  • 06

    Does it support custom intervals?

    Yes, it supports all standard cron formats, including step values.

  • 07

    Can it translate cron to human readable text?
