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.

Curated set · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Music Theory Engine.

  1. 01

    Analyze chord structure

    This capability calculates the specific notes, intervals, and frequencies that make up a chord.

  2. 02

    Get roman numeral

    This capability determines the functional role of a chord within a specific scale.

  3. 03

    Validate enharmonics

    This capability checks if a set of note names is musically legal within a specific scale context.

Real work

What teams actually run

01

Automated Composition

Your agent generates chord progressions that are mathematically valid and harmonically sound.

02

Theory Verification

Check if a specific set of notes fits correctly within a chosen musical scale.

03

Harmonic Analysis

Determine the functional role of chords in a piece of music using Roman numerals.

04

Frequency Mapping

Get the exact 12-TET frequencies for notes to use in digital synthesis.

One connector, every AI

Music Theory Engine 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 Music Theory Engine 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.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Music Theory Engine, so you can see the experience inside your AI.

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

Who it's for

Built for the work Music Theory Engine owners hand off.

This MCP is built for anyone building AI capabilities that require mathematical accuracy in music theory.

  • 01

    Music Composers

    Hand off chord progression logic and scale validation to your agent.

  • 02

    Music Theory Educators

    Use the agent to verify complex harmonic functions and notation accuracy.

  • 03

    Audio Software Developers

    Integrate deterministic musical logic into AI-driven audio applications.

FAQ

Questions Music Theory Engine owners ask.

  • 01

    How does this MCP prevent musical errors?

    It uses deterministic logic to validate enharmonic spellings and chord structures against specific scale rules.

  • 02

    Can I use this with Claude or Cursor?

    Yes, you can connect this MCP to any MCP-compatible client like Claude, Cursor, or Windsurf.

  • 03

    What kind of frequency data does it provide?

    It provides precise 12-TET frequencies for the notes within a chord structure.

  • 04

    Does it support Roman numeral analysis?

    Yes, the get_roman_numeral capability determines the functional role of a chord within a scale.

  • 05

    Is the music theory calculation accurate?

    The engine is designed to be deterministic, providing exact mathematical results for intervals and notes.

  • 06

    How does the engine handle enharmonic spelling?

    The engine uses the provided scale context to determine the correct spelling. For example, it will enforce 'F' instead of 'E#' in a C Major context to maintain musical logic.

  • 07

    What frequency standard is used?

    All frequencies are calculated using 12-tone equal temperament (12-TET) with the standard tuning of A4 = 440Hz.

  • 08

    Can I use this for Roman Numeral analysis?

    Yes, you can use the get_roman_numeral capability to find the functional role and scale degree of any chord within a specific scale.
