How do I use this with Claude?

You connect the MCP through the Vinkius platform. Once connected, your Claude client can call the capabilities directly to perform combat math.

Can this help me optimize my character builds?

Yes. You can use the optimal allocation capability to find the best balance between critical hit chance and flat damage.

Does it work for tabletop games?

Yes. It is designed for any combat system where you need to calculate probabilities and expected damage.

What happens if I enter an impossible stat?

The validation capability will check your parameters and flag any values that are logically impossible.

Is the math deterministic?

Yes. This MCP provides deterministic toolsets for combat mathematics rather than probabilistic AI guesses.

How do I find the best balance between crit and damage?

You can use the calculate_optimal_allocation capability to find the point where marginal crit chance gain equals marginal flat damage gain.

Can I check if my combat stats are valid?

Yes, use validate_combat_parameters to check if your multipliers and base chances are within logical bounds.

What metrics does the hit calculator provide?

The calculate_hit_metrics capability provides final crit chance, expected crits, average damage, damage variance, and the DPS ratio.

Waiting for input…

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 Critical Hit Calculator.

01
Calculate hit metrics
This capability calculates fundamental probability and expected outcomes for your combat stats. It returns data on expected crits and average damage per attack.
02
Calculate optimal allocation
This capability determines the ideal balance between critical hit stats and flat damage. It finds the mathematical sweet spot for your build.
03
Validate combat parameters
This capability checks if your combat configuration contains logically impossible values. It prevents errors in your stat calculations.

Real work

What teams actually run

Character Build Optimization

Determine if you should invest in more flat damage or more critical hit chance for a specific build.

Game Balance Testing

Check how changing a multiplier affects the overall damage output of a character class.

Combat Logic Verification

Run a check on a set of combat stats to ensure no values are logically impossible.

Damage Output Prediction

Calculate the expected average damage over a set number of attacks.

One connector, every AI

Critical Hit 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 Critical Hit 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.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Critical Hit Calculator, so you can see the experience inside your AI.

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