What tuning systems can I compare?

You can compare systems such as Pythagorean, Meantone, and Equal temperament.

Can I use this with Claude or Cursor?

Yes, this MCP works with any MCP-compatible client including Claude, Cursor, and Windsurf.

How does it handle MIDI notes?

The generate_midi_frequency_log capability creates a log for all 128 MIDI notes based on your specified reference frequency.

What is the purpose of the deviation capability?

The calculate_interval_deviations capability finds the cents deviation from Just Intonation for specific intervals.

Do I need to host the MCP myself?

No, Vinkius hosts and manages the MCP for you, so it is ready to use immediately after connection.

What is the range of MIDI notes covered?

The engine covers all 128 MIDI notes, from C-1 to G9.

Can I use a custom reference pitch?

Yes, you can provide any positive frequency in Hz as the referencePitch for all capabilities.

How are deviations calculated?

The calculate_interval_deviations capability compares the selected tuning system against pure Just Intonation ratios and returns the result in cents.

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 Equal Temperament Calculator.

01
Calculate interval deviations
This capability finds the cents deviation from Just Intonation. It is useful for checking how much a specific interval drifts from pure ratios.
02
Compare tuning systems
This capability compares different tuning systems. Use it to analyze the differences between Pythagorean, Meantone, and Equal temperament.
03
Generate midi frequency log
This capability produces a complete MIDI frequency log. It generates a list of frequencies for all 128 MIDI notes based on your chosen reference.

Real work

What teams actually run

Synthesizer Development

Generate frequency logs to test how a digital oscillator responds to different tuning settings.

Music Theory Research

Compare the interval purity of Meantone versus Equal temperament for specific chords.

Acoustic Modeling

Calculate cents deviations to understand how much a tuning system drifts from pure ratios.

Digital Instrument Design

Use MIDI frequency logs to map out the pitch range of a new virtual instrument.

Automate a task

Put Equal Temperament Calculator to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

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

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