How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: signatures are present but failed validation. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 758 tokens (~126/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
convert_breath_blood_alcohol Convert breath alcohol and blood alcohol ~112
Convert 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 equivalent, not a measurement.

drink_driving_limits_europe Drink-driving limits in Europe ~82
Blood 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.

drinks_to_reach_permille Drinks to reach a permille level ~184
How 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 spread over that time and the level is the one reached at its end. Drink: an id from list_drinks, or ml + vol. Answers a question about amounts, never about whether driving is safe.

estimate_blood_alcohol Estimate blood alcohol (permille) ~177
Estimate 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 conservative hours until below 0.5, 0.3 and 0.0 permille. Drinks: either an id from list_drinks or ml + vol (percent ABV).
