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 Drop Rate Calculator.

  1. 01

    Analyze expected resource usage

    This capability calculates how many runs you can expect to perform before succeeding and provides an efficiency ratio.

  2. 02

    Estimate confidence thresholds

    Use this to find the minimum number of attempts required to hit 10%, 50%, or 90% success probability.

  3. 03

    Calculate cumulative probability

    This capability determines the probability of getting at least one success within a specific number of attempts.

Real work

What teams actually run

01

Gacha Pull Planning

Calculate if you have enough currency to reach a 90% chance of pulling a specific character.

02

Loot Table Testing

Verify that drop rates in a game design meet the intended statistical targets.

03

Pity Progress Tracking

Determine how many more runs are needed to hit a guaranteed drop in a pity system.

04

Efficiency Auditing

Compare expected resource usage against actual results to check luck status.

Automate a task

Put Drop Rate Calculator 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

Drop Rate Calculator 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 Drop Rate Calculator 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. 3 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 Drop Rate Calculator, so you can see the experience inside your AI.

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

Who it's for

Built for the work Drop Rate Calculator owners hand off.

This MCP is built for anyone dealing with randomized reward systems in gaming.

  • 01

    Game Developers

    They hand off loot table math to the AI to verify drop rates and pity mechanics.

  • 02

    Hardcore Gamers

    They use the AI to calculate how many resources are needed for specific gacha or loot pulls.

  • 03

    Data Analysts

    They use the capability to model probability distributions for randomized reward systems.

FAQ

Questions Drop Rate Calculator owners ask.

  • 01

    How do I use this with Claude?

    You connect the MCP through the Vinkius platform. Once connected, you can simply ask Claude questions about drop rates or pity mechanics in your normal chat.

  • 02

    Can it handle pity systems?

    Yes, the capability includes functionality to analyze expected resource usage and remaining effort when pity mechanics are in place.

  • 03

    What is a confidence threshold?

    It is the number of attempts required to reach a specific level of certainty, such as a 50% or 90% chance of success.

  • 04

    Do I need to provide the drop rate?

    Yes, you must tell your AI client the specific drop rate or probability you want to calculate.

  • 05

    Is this for game developers or players?

    It works for both. Developers use it to test loot tables, while players use it to plan their resource spending.

  • 06

    How does the calculator handle pity systems?

    If you provide a pityThreshold in any capability, the calculation accounts for a guaranteed success at that specific trial number, effectively capping the maximum possible failure streak.

  • 07

    What does the efficiency ratio mean?

    In analyze_expected_resource_usage, an efficiency ratio greater than 1.0 indicates that your current number of unsuccessful runs has exceeded the statistical average, meaning you are currently 'unlucky'.

  • 08

    Can I use this for Gacha games?

    Yes, the calculator is ideal for any system using Bernoulli trials, such as Gacha pulls, loot boxes, or boss drops with fixed or pity-based rates.
