Does this MCP handle daylight saving time changes?

Yes. It uses UTC-based integer math to ensure event sequences remain consistent regardless of local timezone shifts or daylight saving transitions.

What clients can I use with this MCP?

You can use this MCP with any compatible client, including Claude, Cursor, Windsurf, and VS Code.

Can I use this to check if my calendar strings are broken?

Yes. You can use the audit_rule_syntax capability to verify that your RRULE strings follow the correct structural syntax.

How do I get a list of all future dates for a recurring event?

Use the calculate_event_dates capability. You provide the RRULE and a start date, and it returns the chronological list of occurrences.

Do I need to host this myself?

No. Vinkius hosts and manages the MCP for you. You just connect your client and it is ready to use.

How does the engine handle timezone changes?

The engine uses UTC-based integer math via the V8 Date object, ensuring that all calculations are deterministic and unaffected by local timezone shifts or daylight saving transitions.

Can I verify if my RRULE string is valid before processing it?

Yes, you can use the audit_rule_syntax capability to check for structural errors like missing FREQ properties or malformed intervals.

What parameters can I extract from a rule?

By using decompose_rrule, you can extract key-value pairs such as FREQ, INTERVAL, COUNT, and UNTIL to understand the rule's configuration.

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.

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 iCalendar RRULE Iterator.

01
Decompose rrule
This capability breaks an RRULE down into its individual components. It lets your agent see specific parts like frequency and interval.
02
Audit rule syntax
This capability checks an RRULE string for structural errors. It ensures the syntax follows correct iCalendar standards before you try to use it.
03
Calculate event dates
This capability generates a chronological list of timestamps based on a specific RRULE and start date.

Real work

What teams actually run

Automated Calendar Sync

Your agent can parse incoming calendar invites and expand them into actionable task lists.

Subscription Management

Calculate exact billing dates for customers on recurring monthly or yearly cycles.

Scheduling Bot Development

Give your agent the ability to accurately predict when the next meeting in a series occurs.

Data Integrity Audits

Verify that exported calendar files contain valid and logical recurrence patterns.

One connector, every AI

iCalendar RRULE Iterator 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 iCalendar RRULE Iterator 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 iCalendar RRULE Iterator, so you can see the experience inside your AI.

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