A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
destinations
list_destinations
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.
flats
get_flats
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.
plan
plan_trip
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.
price
price_grid
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
quote_flat
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
recommend_config
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.
shop
get_shop_facts
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.
start
start_checkout
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.

How MCP servers expose tools in the first place →
Is roamflat Flat configurator working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 318 ms. The bar chart above shows every period we have measured.
Did roamflat Flat configurator ever remove tools?
Yes. get_plan_details, recommend_plan, search_esim_plans are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect roamflat Flat configurator?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does roamflat Flat configurator need an API key?
No. roamflat Flat configurator completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is roamflat Flat configurator?
It answers our handshake in 318 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
