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 Security83
- 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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 3552 tokens (~322/item across 11 items; 8 tools + 3 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 Management40
- Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (25% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

get_flats Flats of a country ~209
The networks of one country (operator, 5G) and the Flats built from them — each Flat with the networks it includes and the price for every speed for the given days (null = that speed needs a 5G network). Use to explain the choice between networks and speeds.
| Name | Type | Req | Description |
|---|---|---|---|
| bucket | string | – | Optional language-region bucket the customer shops in, e.g. en-gb, de-de (sets currency and link locale). Defaults from language. |
| currency | string | – | Optional ISO 4217 override for prices. |
| days | integer | – | Days of mobile data (1–30). |
| destination | string | yes | Country in ANY language or its ISO code, e.g. "Japan", "Japon", "jp". Map a city to its country first. One country per Flat. |

No output schema declared.
No examples provided.
get_shop_facts Shop facts ~139
What roamflat is and how the Flat works, in the shop's own words: speeds, networks, when the days start, delivery, payment, refund policy, adding days, My Flat, e-mails, app, devices, support. Use for any question that is not a price.

No output schema declared.
No examples provided.
list_destinations List destinations ~147
Every country roamflat builds a Flat for, with the number of networks, whether 5G (and so 25/50 Mbps) is available, and the starting price per day (5 Mbps, cheapest network). Use to check coverage or compare countries.

plan_trip Plan a multi-country trip ~383
A trip through several countries (max 5): one Flat per country, each quoted at the same speed and days unless given per country. days is PER COUNTRY, never the whole trip: for a 12-day trip through Japan and Thailand pass per_country days that add up to 12 (e.g. 7 + 5). Returns one line per country with price and buy_url, plus the total. Use when the customer names two or more countries and a speed (2–5 destinations); for one country call quote_flat; use recommend_config when they describe devices or usage instead.

| per_country | array | – | Optional overrides per country (days and/or mbps). Use it to split the trip: the days of all countries together should add up to the trip length. |
No output schema declared.
No examples provided.
price_grid Price grid ~303
Prices for several speed × days combinations of one Flat in one call (up to 8 day values; speeds default to all), e.g. to compare with other providers or to find the best fit. Same server prices as quote_flat.

quote_flat Quote one Flat ~341
Use while the customer is still deciding — "how much is …?": the exact price of one configuration (country, speed, days and optionally which Flat / networks), the server price the customer would pay. Quote it as returned, never compute or scale it yourself. The result carries a buy_url for reference; when the customer says they want to buy, call start_checkout instead.

recommend_config Recommend a Flat ~557
Use when the customer describes the trip instead of a speed: country (or up to 5), days and what will be connected (devices: phone, phone_laptop, small_group, family, creator_posting, creator_live, creator_hd_live, creator_pro). Picks the speed from the roamflat speed guide and returns it server-quoted together with the step below and the step above (where offered), each with price, networks, a one-line reason and its buy_url, plus trip totals and an optional budget check. A speed that needs 5G in a country without 5G falls back to the highest speed there and says so. Prices are the same as quote_flat. Give destination (one country) or destinations (several) — one of the two is required; a call without a country fails with invalid_argument.

start_checkout Start secure checkout ~388
Use only once the customer has decided to buy ("I'll take it", "how do I buy?"): the checkout handoff. Returns the buy_url to give the customer, the final price and a ready-to-send checkout block (next_step, payment_methods, delivery) — on the page they press the buy button (buy_button, e.g. "Get your Flat" in English) and pay securely. No account needed; the eSIM is delivered on screen and by email within seconds of payment. No in-chat order tracking, no discount codes. For prices while the customer is still comparing, use quote_flat.
