MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Blood alcohol estimates, drinks per permille level, breath/blood conversion, DE + EU driving limits
These three are never merged into one score: opinions, measurements and popularity are different things.

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.
estimate_blood_alcoholEstimate blood alcohol concentration in permille (g/kg, the German unit; 0.5 permille = 0.05 % BAC) from body data and drinks, using Widmark with Watson body water, a 10-30 % resorption deficit and 0.1-0.2 permille/h elimination. Returns the peak and current value as a range and
list_drinksTypical German drink servings with volume, alcohol by volume and grams of pure alcohol. Use the ids in estimate_blood_alcohol.
german_drink_driving_limitsThe blood alcohol limits in German road traffic (0.0, 0.3, 0.5, 1.1, 1.6 permille): who they apply to and the legal consequences (fines, points, driving bans, criminal offence). Text in German.
drinks_to_reach_permilleHow many servings of a drink bring a person to a given blood alcohol level (e.g. "how many beers are 0.5 permille"), as a range: the low end assumes a 10 % resorption deficit and slow elimination, the high end 30 % and fast elimination. With hours_of_drinking > 0 the drinks are s
convert_breath_blood_alcoholConvert breath alcohol (mg/l, what a roadside breathalyser measures) to blood alcohol (permille) or back, at the German legal ratio 1:2000 (0.25 mg/l = 0.5 permille). Give exactly one of breath_mg_per_l or blood_permille. The individual ratio varies, so the result is the legal eq
drink_driving_limits_europeBlood alcohol limits for car drivers in 25 European countries, with the stricter limits for novice, young or professional drivers. Optional country: ISO code (AT, IT, GB-ENG, GB-SCT …) or German or English name; without it, all countries. Country names and notes in German.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 12 days ago.
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.
