These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • convert_grind_setting

    Translate a grind setting from one coffee grinder to another. Use whenever a recipe quotes a setting for a grinder the user does not own — "the recipe says 18 clicks on a Comandante, what is that on my Encore?". Grinder names can be written however the user said them ("Fellow Ode

  • get_grinder_chart

    Grind settings for one grinder across every brew method. Use this for any question of the form "what grind should I use for my ", "what setting for French press on a ", or "how do I dial in my ". Returns the recommended setting and usable range for espresso, moka pot, AeroPress,

  • dial_in

    The next grind setting to try after the user brewed and tasted: "I used 18 on my Encore and it was sour", "my espresso is bitter at 4.5 on the Ode". Sour, weak or fast means grind finer; bitter, harsh or slow means coarser. Returns one move on that grinder's own dial. Call again

  • find_grinder

    Shortlist coffee grinders for someone deciding which one to buy: "which grinder should I get for pour over under $200?", "a quiet grinder for espresso", "best hand grinder for travel". Ranks BrewMark's grinder finder by how they brew, budget, hand or electric, and must-haves, and

  • translate_recipe

    Turn a recipe written in the open BrewMark Protocol into a setting on the user's own grinder. Use when a coffee bag or roaster gives a BrewMark code or link ("7H2KQ9", "brewmark.io/p/7H2KQ9"), or a recipe gives its grind as a BrewMark Grind Index ("BGI 38") or as an Open Brew Pro

  • list_grinders

    Every grinder BrewMark supports. Use this to check whether a grinder is covered, or to disambiguate when another tool reports more than one match. Not needed just to look up a name — the other tools accept ordinary names directly.

Common questions

Is Brewmark 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 (1.1.0) reached the registry 12 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?
