What can this MCP calculate?

It calculates empirical formulas, molecular formulas, and the degree of unsaturation.

How do I use mass percentages with this capability?

You use the derive_from_composition capability to convert mass percentages into a molecular formula.

Which AI clients can use this MCP?

Any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code can use this.

Do I need to host the MCP myself?

No, Vinkius hosts and manages the MCP for you. You just connect your client and start using the capabilities.

Can it help with mass spectrometry data?

Yes, the capabilities are specifically designed to help researchers process elemental composition and mass spectrometry data.

How do I calculate the molecular formula?

You can use the calculate_molecular_formula capability by providing the empirical formula and the target molar mass.

Can I use mass spectrometry data?

Yes, the calculate_molecular_formula capability accepts an optional msMassData parameter to refine the molar mass using the molecular ion peak.

What is the degree of unsaturation?

The degree of unsaturation represents the total number of rings and pi bonds in a molecule, which can be found using calculate_unsaturation.

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 Molecular Formula Determination.

01
Calculate molecular formula
This capability derives the actual molecular formula by applying known mass data to an empirical formula.
02
Calculate unsaturation
Use this to find the degree of unsaturation for any specific molecular formula.
03
Derive from composition
This capability converts mass percentages directly into a molecular formula.
04
Find empirical formula
This capability determines the simplest whole-number ratio of elements based on their masses.

Real work

What teams actually run

Mass Spectrometry Analysis

An agent takes raw mass data and uses the capabilities to identify the resulting molecular formula.

Elemental Composition Tasks

You provide mass percentages of elements and the AI returns the empirical formula.

Structural Verification

The AI calculates the degree of unsaturation to help narrow down possible molecular structures.

Stoichiometry Homework Help

Students use the capabilities to check their work on empirical and molecular formula problems.

One connector, every AI

Molecular Formula Determination 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 Molecular Formula Determination 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 Molecular Formula Determination, so you can see the experience inside your AI.

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