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.

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.
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.
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 · 4 capabilities
We ship only the actions that matter.
01-04
4 capabilities in this set.
Part of 4 available through Cron Expression Engine.
- 01
Convert format
This capability changes a cron expression from one standard to another. It's useful for moving schedules between different cloud or system environments.
- 02
Validate cron
This capability checks if a cron expression follows the correct syntax for its specific format. It catches errors like out-of-range values before you deploy them.
- 03
Calculate schedule
This capability computes upcoming or recent execution timestamps. You can use it to see exactly when a scheduled event will trigger.
- 04
Parse and explain
This capability breaks down a cron string into human-readable parts. It tells you exactly what each field in the expression represents.
Real work
What teams actually run
CI/CD Pipeline Setup
Your agent can generate and verify GitHub Actions schedules to ensure builds run at the right time.
Cloud Event Management
Use the AI to convert standard cron strings into AWS CloudWatch compatible formats.
Application Task Debugging
The AI can explain why a specific Quartz expression isn't behaving as expected by parsing its fields.
Automation Testing
Verify that your scheduled scripts will trigger on the correct days and times before deployment.
One connector, every AI
Cron Expression Engine 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.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put Cron Expression Engine 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. 4 capabilities arrive 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 Expression Engine, so you can see the experience inside your AI.
It does not authenticate your account with Cron Expression Engine. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions Cron Expression Engine owners ask.
- 01
What cron standards does this MCP support?
It supports Unix, Quartz (Spring), AWS CloudWatch, and GitHub Actions standards.
- 02
Can I use this with Claude or Cursor?
Yes, you can use this with any MCP-compatible client including Claude, Cursor, Windsurf, and VS Code.
- 03
How do I check if my cron expression is valid?
You can ask your AI client to use the validate_cron capability to check the syntax for a specific format.
- 04
Does this MCP host the logic?
Yes, Vinkius hosts the MCP and manages everything so it is ready to use as soon as you connect.
- 05
Can it help me convert Unix cron to AWS cron?
Yes, you can use the convert_format capability to transform expressions between these different standards.
- 06
What cron formats are supported?
The engine supports Unix (5-field), Quartz (6 or 7-field), AWS CloudWatch, and GitHub Actions formats.
- 07
How can I check if my cron expression is valid?
You can use the validate_cron capability. Simply provide your expression and specify which format (e.g., 'unix' or 'aws') you are using.
- 08
Can I convert a Unix cron to AWS CloudWatch format?
Yes, the convert_format capability is designed specifically for this. It handles the structural differences between standards while maintaining the same schedule.
