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

We ship only the actions that matter.

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Song Key Transposer.

  1. 01

    Validate key existence

    Checks if a specific musical key name is valid. It ensures your agent doesn't attempt to transpose using non-existent keys.

  2. 02

    Get transposition interval

    Calculates the semitone distance between two musical keys. This helps your agent understand how far to shift a progression.

  3. 03

    Parse chord symbol

    Breaks a single chord string into its individual parts. It identifies the root, accidentals, and quality of a chord.

  4. 04

    Transpose chords

    Shifts a full sequence of chords from a starting key to a target key. This is the primary capability for rewriting progressions.

Real work

What teams actually run

01

Vocal Range Adjustment

You can tell your agent to transpose a song to a lower key to fit a specific singer.

02

Theory Analysis

Use the parsing capability to understand the components of difficult jazz chords.

03

Composition Assistance

Quickly test how a progression sounds in a different key by shifting the entire sequence.

04

Data Cleaning

Standardize chord notation by breaking symbols down into their constituent parts.

FAQ

Questions Song Key Transposer owners ask.

  • 01

    How do I use this with Claude?

    You connect the MCP through the Vinkius platform. Once connected, your Claude client can call the transposition and parsing capabilities directly.

  • 02

    Can it handle complex jazz chords?

    Yes, the parse_chord_symbol capability is designed to break down chord strings into their roots, accidentals, and qualities.

  • 03

    Does it work with any musical key?

    The validate_key_existence capability ensures that the keys being used are valid musical keys before any operations occur.

  • 04

    What is a semitone interval?

    It is the distance between two notes. The get_transposition_interval capability calculates this distance between keys for you.

  • 05

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP, so it is ready to use as soon as you connect your client.

  • 06

    How do I transpose a song?

    You can use the transpose_chords capability by providing the original chord sequence, the source key, and the target key.

  • 07

    Can I choose between sharps and flats?

    Yes, when using transpose_chords, you can set the preferSharps parameter to true or false to control the accidental preference.

  • 08

    What happens if I provide an invalid key?

    The validate_key_existence capability will check if the key is valid. If you attempt to transpose using an invalid key, the capability will return an error.
