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.

FAQ

Questions Cycle Day Resolver owners ask.

  • 01

    What is the Cycle Day Resolver MCP used for?

    It is a capability for calculating which step in a repeating sequence falls on a specific date. It works with any ordered list of tasks and a starting date.

  • 02

    Can I use this with Claude or Cursor?

    Yes. You can connect this MCP to any MCP-compatible client like Claude, Cursor, or Windsurf through the Vinkius platform.

  • 03

    Do I need to host the MCP myself?

    No. Vinkius hosts and manages the MCP for you. You just connect your client and start using the capabilities.

  • 04

    Does it work with cycles of different lengths?

    Yes. The MCP is designed to handle variable-length sequences based on the array of steps you provide.

  • 05

    How do I get a list of all upcoming tasks?

    You can use the get_schedule_window capability to generate a complete chronological forecast for a specific time range.

  • 06

    How does the cycle resolution logic work?

    The engine calculates the number of days elapsed between your anchor start date and the target date, then finds the remainder when divided by the total cycle length to identify the correct step.

  • 07

    Can I use this for skincare routines?

    Yes, you can provide a cycle array like ['Retinol', 'Exfoliant', 'Recovery'] and an anchor date to determine exactly which product to use on any future morning.

  • 08

    What happens if the target date is before the start date?

    The get_step_for_date capability will return an error stating that the target date must be equal to or later than the anchor date.
