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 · 4 capabilities

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Chord Constructor.

  1. 01

    Generate voicings

    This capability arranges a set of notes into specific musical textures. It produces both closed and open voicings based on your requirements.

  2. 02

    Get chord inversions

    This capability calculates all possible permutations of a chord. It returns the bass note and the full stack for every inversion.

  3. 03

    Parse chord string

    This capability converts a standard chord name into its structural parts. It returns the root, the intervals, and a normalized name.

  4. 04

    Determine harmonic role

    This capability identifies how a chord functions within a specific musical key.

Real work

What teams actually run

01

Automated Arrangement

Your agent can take a chord progression and generate open voicings to fill out a musical texture.

02

Theory Research

Use the AI to quickly find all possible inversions for a specific set of notes.

03

Composition Assistance

Ask your agent to identify the harmonic role of a chord to ensure it fits your intended key.

04

Notation Parsing

Convert complex chord strings into structured data for use in other musical software.

Automate a task

Put Chord Constructor 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

Chord Constructor 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 Chord Constructor 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.
