Gas blending calculator for scuba divers: nitrox, trimix, heliair, heliox, MOD, best mix and fills.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • blend

    Use whenever the user asks how to blend, mix, fill or prepare a breathing gas, even if they don't mention In Da Mix. Step-by-step fill plan for blending nitrox, trimix, heliair or heliox into a scuba tank, from what is in it now to the mix and pressure wanted: how much helium and

  • gas_usage

    For one blend: the litres of each gas it takes from the banks, each bank's pressure afterwards, and whether a bank can still decant (or needs boosting, or runs short). Same inputs as blend, plus the banks. Use for "how much helium will this fill use", "is my O2 bank enough for th

  • fills_from_bank

    How many identical fills the source banks give before a bank can't supply the next one, and why it stops (bank down to the minimum pressure, or it can't decant high enough without a booster). Every tank is assumed to start the same (start_pressure / mix). Use for "how many tanks

  • top_up

    Top a tank up with a ready-made supply gas (air, EAN32, a trimix premix…): the pressure added, the mix you end up with, its MOD, and the gas density at a depth. For a ready-made supply gas; to add pure oxygen or helium use what_if or blend. Use for "I have 50 bar of EAN32 left, w

  • best_mix

    Use this FIRST when the user asks which breathing gas to use for a planned depth, or to select, recommend, optimise or compare one, even if they don't mention In Da Mix. The best nitrox or trimix for a planned depth within the diver's limits, as an open-circuit bottom gas or as C

  • mod

    Use whenever the user asks how deep a gas can go or checks an existing breathing gas (nitrox, trimix, CCR diluent) against a depth, even if they don't mention In Da Mix; never work a MOD out by hand. Maximum operating depth of a breathing gas: the MOD by the ppO2 limit (as on a c

  • what_if

    What mix you get when you add given pressures of oxygen, helium and/or air to what is in the tank (the app's What If): the pressure after each addition, the resulting mix, its MOD, EAD, END and gas density. Use for "what if" additions: "I have 50 bar of air, what do I get if I ad

  • decant

    Decanting one gas (oxygen, or helium) from source cylinders into a small cylinder without a compressor, as the app's Decant: a cascade, each cylinder equalised in turn (ideal gas). plan refills: one refill or a series (e.g. a CCR O2 cylinder from 75 to 150 bar after every dive):

  • list_methods

    The calculation methods (equations of state) In Da Mix offers, with their ids for the method input. The current default is in the `default` field. Use when the user asks about calculation models: ideal versus real gas, compressibility, Z-factors, Peng-Robinson, MultiDeco. Use for

Common questions

Is In Da Mix safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.26.41) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Kanal Varna — drains, leaks & plumbing (Varna, BG)
