historical_airlines — Historical airlines of a year
Advertised by the server during the last successful anonymous check.
Advertised read-only

Real 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_catalog — Aircraft catalog
Advertised by the server during the last successful anonymous check.
Advertised read-only

Aircraft 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_price — Aircraft price in a game year
Advertised by the server during the last successful anonymous check.
Advertised read-only

In-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.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http jetopolis-mcp https://jetopolis.app/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add jetopolis-mcp --url https://jetopolis.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable jetopolis-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "jetopolis-mcp": {
      "url": "https://jetopolis.app/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "jetopolis-mcp": {
      "type": "streamableHttp",
      "url": "https://jetopolis.app/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start jetopolis-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "jetopolis-mcp": {
      "type": "http",
      "url": "https://jetopolis.app/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http jetopolis-mcp https://jetopolis.app/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://jetopolis.app/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "jetopolis-mcp": {
      "serverUrl": "https://jetopolis.app/mcp"
    }
  }
}
