How do I use this MCP with Claude?

You connect your Claude client to Vinkius once, and the Fertilizer Calculator capabilities become available for your agent to use immediately.

Can this MCP help reduce fertilizer costs?

Yes, the recommend_fertilizer_blend capability specifically looks for the most cost-effective combinations of fertilizers to meet your nutrient needs.

Does it support different nutrient representations?

Yes, you can use the convert_nutrient_forms capability to switch between elemental nutrients and oxide representations like P2O5.

What kind of data do I need to provide?

You typically provide soil test values, target crop types, and expected yields to get accurate nutrient gap calculations.

Do I need to host the MCP myself?

No, Vinkius hosts and manages the MCP for you, so it is ready to use as soon as you connect your client.

How do I calculate the nutrient gap for my crop?

You can use the calculate_nutrient_gap capability. Provide the crop type, target yield, and the current soil nutrient levels to get the exact N, P2O5, and K2O requirements.

Can I get recommendations for specific fertilizer products?

Yes. Once you have calculated your nutrient gap, use the recommend_fertilizer_blend capability along with your available fertilizer catalog to find the cheapest combination.

What is the difference between elemental and oxide forms?

Agricultural products often use oxide forms like P2O5 and K2O. You can use convert_nutrient_forms to translate between these and elemental N, P, or K.

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.

This capability suggests the cheapest combination of available fertilizers to fill your calculated nutrient gap.
04
Calculate nutrient gap
This capability finds the exact N, P2O5, and K2O amounts needed to meet specific crop requirements based on current soil levels.

Real work

What teams actually run

Pre-planting Planning

Calculate the exact nutrients needed for a specific crop before the season starts.

Cost Reduction

Find the cheapest way to hit NPK targets using your current fertilizer inventory.

Soil Test Interpretation

Convert raw soil analysis numbers into actionable application rates.

Yield Modeling

Determine how much nutrient removal a specific yield target will require.

One connector, every AI

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

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