An MCP is an open standard that lets your AI client connect to external capabilities. Vinkius hosts this MCP so you can use it instantly in Claude, Cursor, or Windsurf.

Can I use this for any gacha game?

Yes. As long as you know the base rates, soft pity start points, and hard pity limits, you can model the mechanics for any game.

Does this predict my actual luck?

No. It uses mathematical probability to show you the expected number of pulls and the cost to reach certain confidence levels.

How do I connect this to Claude?

You connect once through the Vinkius interface, and the capabilities become available to your client automatically.

Soft pity is a mechanic where the success rate increases after a certain number of unsuccessful pulls. This MCP can model those specific ramps.

What is the difference between expected pulls with and without pity?

Without pity, the expected number of pulls is simply the inverse of the base rate. With pity, the calculate_pint_metrics capability accounts for the increased probability during the soft pity period and the 100% guarantee at hard pity, typically resulting in a much lower average pull count.

How can I estimate how much currency I need for a specific item?

You can use the estimate_budgetary_impact capability. By providing your currency cost per pull and a probability curve generated by generate_probability_curve, you can see the average cost and the cost required to reach specific confidence levels like 90% or 99%.

Does this simulator support soft pity mechanics?

Yes, the simulator is specifically designed to model soft pity. You can define a threshold where the rate begins to increase and specify the increment amount per pull.

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

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Gacha Pity Simulator.

01
Calculate pity metrics
This capability calculates the expected number of pulls required both with and without active pity systems.
02
Generate probability curve
Use this to create a cumulative probability curve that shows your chances of success over a series of pulls.
03
Estimate budgetary impact
This capability calculates the total financial or in-game currency cost based on your pull probability data.

Real work

What teams actually run

Resource Planning

Determine exactly how many gems you need to save to hit a 95% success rate for a new banner.

Mechanic Testing

Compare how a 1% base rate performs against a 2% base rate when soft pity is applied.

Budgeting

Estimate the total cost of a character pull sequence before you start spending.

Probability Visualization

Generate curves to see where the most likely success windows occur in a pull cycle.

Automate a task

Put Gacha Pity Simulator 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

Gacha Pity Simulator 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 Gacha Pity Simulator 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 Gacha Pity Simulator, so you can see the experience inside your AI.

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