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.

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.

FAQ

Questions Transposition Calculator owners ask.

  • 01

    How do I use this with Claude?

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

  • 02

    Can it handle Bb and Eb instruments?

    Yes. The apply_instrument_notation capability is specifically designed to adapt concert pitch for Bb, Eb, and F instruments.

  • 03

    Does it work for entire songs?

    You can use the transpose_progression capability to move entire sequences of music at once.

  • 04

    What happens if a note is spelled incorrectly in a new key?

    The resolve_enharmonic_spelling capability ensures that the notation follows standard musical rules for the target key.

  • 05

    Do I need to host this myself?

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

  • 06

    What musical elements can I transpose?

    You can transpose individual notes, chords (including complex qualities like maj7), scales, and entire progressions using the transpose_element or transpose_progression capabilities.

  • 07

    How does it handle transposing instruments?

    The apply_instrument_notation capability automatically calculates the correct written notation for Bb (e.g., Trumpet), Eb (e.g., Alto Sax), and F (e.g., French Horn) instruments based on a provided concert pitch.

  • 08

    Can it resolve enharmonic duplicates?

    Yes. By using resolve_enharmonic_spelling, you can provide a scale context (like 'G Major') to ensure that notes like A# are correctly spelled as Bb for better musical readability.
