Airline strategy game 1950-2030: live worlds, leaders, historical airlines, aircraft prices
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 45 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.

The tools it lists (7, as of 5 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
list_worldsPublic Jetopolis worlds open right now: name, server region, pace (Standard: 1 game day = 20 real minutes, Blitz: 5), start and end year, current game date and era, players and seats, players active in the last 24 hours, and a link to open the world. Worlds never pause.
get_worldOne Jetopolis world by id: the same card as in list_worlds plus finishedAt for a world that has ended.
world_standingsPlayer airlines of a world ranked by rating: airline name and two-letter code, home base, rating, aircraft in service, open routes, founding date, status and a link to the public airline card. Updated once per game day of that world. Cash, fares and profit are private to each player and are never returned.
historical_airlinesReal airlines that operated in a given year (1950-2030) as the game knows them: name, IATA code when reliably known, home country and region, type, years of operation, and the countries each one served that year. Network data has decade precision: a country listed for the 1960s may have been added mid-decade. servedCountries lists destinations from home; when networkKnown is false only the home country is known. Sorted by the airline size in the dataset.
aircraft_catalogAircraft types of the game catalog: seats in two classes, range, cruise speed, required runway, entry into service and end of production, and the list price in millions of US dollars of the entry-into-service year. With year, only types already flying that year are returned and availabilityInYear says whether they are sold new or only on the used market.
aircraft_priceIn-game catalogue price of a new aircraft in a given year: the entry-into-service price inflated by US CPI to nominal dollars of that year, and the same price in 2024 dollars. Accepts an id from aircraft_catalog or part of the name; when several types match and the year does not settle it, returns candidates to choose from.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
app.jetopolis/game, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
