How do I use this MCP with my AI client?

You connect your client to Vinkius once, and the capabilities become available for your agent to call whenever you provide brewing data.

Can this MCP help me fix a sour espresso shot?

Yes, by using the analyze_extraction capability, your agent can determine if your extraction yield is too low, suggesting you might need a higher yield or different dose.

What data do I need to provide for a dose adjustment?

You should provide your target yield, your desired beverage weight, your target TDS, and your current dose.

Does this capability work with any AI client?

It works with any MCP-compatible client like Claude, Cursor, or Windsurf.

What happens if I enter impossible brewing numbers?

The validate_extraction_parameters capability will identify if the parameters are physically impossible, such as a yield exceeding 100%.

How do I know if my espresso is underextracted?

You can use the analyze_extraction capability. If the extraction yield is below 18%, the shot is classified as underextracted, which often tastes sour.

How can I adjust my dose to reach a target yield?

Use the calculate_dose_adjustment capability. Provide your current dose, the target yield, the beverage weight, and the TDS to find the required dose change.

What is a realistic TDS for espresso?

Typically, espresso TDS falls between 6% and 12%. You can use validate_extraction_parameters to check if your measurements are within reasonable bounds.

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

01-03

3 capabilities in this set.

Part of 3 available through Espresso Extraction Calculator.

01
Analyze extraction
This capability evaluates your current espresso profile. It processes dose, yield, and TDS to determine your current extraction yield and strength.
02
Calculate dose adjustment
This capability calculates the exact coffee dose needed to reach a specific target extraction yield. It uses your current parameters to suggest precise weight changes.
03
Validate extraction parameters
This capability checks if your brew data is mathematically possible. It prevents you from attempting shots where the yield would exceed 100%.

Real work

What teams actually run

Dialing In New Coffee

Input your first shot data to see if you are over or under-extracting.

Targeting Specific Yields

Calculate the exact dose needed to hit a 21% yield for a specific roast.

Troubleshooting Sour Shots

Use extraction analysis to see if your yield is too low for the current dose.

Consistency Checks

Verify that your daily shots are hitting the same TDS and yield targets.

One connector, every AI

Espresso Extraction 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 Espresso Extraction 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.
