How do I use this MCP with Claude or Cursor?

You connect your client to Vinkius once, and the capabilities become available as functions your agent can call during a conversation.

Does this MCP handle Tafel slope calculations?

Yes, the activation overpotential capability uses the Tafel approximation to provide these values.

Can I calculate total voltage loss in one step?

Yes, the total overpotential capability sums kinetic, mass transport, and resistive components for you.

What kind of electrochemical data do I need to provide?

Depending on the capability, you will need values like current density, exchange current density, limiting current density, or internal resistance.

Is there any setup required on my local machine?

No, Vinkius hosts the MCP, so you only need to connect your client to the Vinkius endpoint.

What is activation overpotential?

It is the voltage required to overcome the energy barrier for the charge transfer reaction at the electrode surface.

How do I calculate total voltage loss?

You can use the calculate_total_overpotential capability by providing the individual activation, concentration, and ohmic loss values.

Does this capability account for ohmic losses?

Yes, the calculate_ohmic_loss capability specifically calculates voltage drops caused by the internal resistance of cell components.

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.

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Overpotential Calculator.

01
Calculate concentration overpotential
This capability calculates concentration overpotential caused by mass transport limitations.
02
Calculate activation overpotential
This capability uses the Tafel approximation to find activation overpotential.
03
Calculate total overpotential
This capability computes the total voltage loss by combining kinetic, mass transport, and resistive components.
04
Calculate ohmic loss
This capability determines the ohmic loss resulting from internal resistance in a cell.

Real work

What teams actually run

Fuel Cell Efficiency Testing

Calculate how much voltage is lost to mass transport as current density increases.

Battery Impedance Analysis

Use the ohmic loss capability to quantify the impact of internal resistance on performance.

Electrolyzer Optimization

Determine activation overpotential to optimize electrode materials for lower energy consumption.

Kinetic Modeling

Use the Tafel approximation to derive kinetic parameters from experimental current density data.

One connector, every AI

Overpotential 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 Overpotential 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 Overpotential Calculator, so you can see the experience inside your AI.

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