SoloWay MCP Server

Live intercity bus-trip search across Ukraine and Europe as a remote MCP server. Read-only, no API key, no auth. Powered by soloway.com.ua — bookings are completed there, not through the tools.

Remote endpoint: https://mcp.soloway.com.ua/mcp (streamable HTTP, stateless)

Tools

Tool	What it does
search_trips	Trips between two cities on a date — live prices, free seats, carriers, duration, transfers, passenger discounts, and a booking deep-link. City names resolve automatically (uk/en), with disambiguation when several cities match.
get_calendar_prices	Cheapest price for each day of a month on a route — find the cheapest day to travel.
get_trip_details	Full details of one trip from search results — stops, carrier discounts, seat info.
ping	Liveness check.

All tools declare outputSchema, readOnlyHint: true and openWorldHint: false.

Connect

Works with any MCP client that speaks streamable HTTP. Step-by-step instructions for Claude, ChatGPT and others: soloway.com.ua/connect.

Claude Code:

claude mcp add --transport http soloway https://mcp.soloway.com.ua/mcp

Self-hosting

The server is a thin, cache-friendly proxy over the public SoloWay API — the Docker image works out of the box:

docker build -t soloway-mcp .
docker run -p 8088:8088 soloway-mcp
# then point your MCP client at http://localhost:8088/mcp

Configuration

All settings are env vars with sane defaults — see .env.example. The ones you may care about:

Var	Default	Notes
PORT	8088	HTTP port
BACKEND_BASE_URL	https://soloway.com.ua (image)	SoloWay API origin
EXPECTED_HOST	* (image)	CSV of accepted Host values for no-Origin requests. * accepts any host and disables the SDK DNS-rebinding belt — fine for local/sandbox runs; pin your public hostname in production (our prod sets mcp.soloway.com.ua).
ALLOWED_ORIGINS	claude.ai / openai.com / soloway.com.ua	CSV, suffix wildcards supported (https://*.claude.ai)
DEFAULT_LOCALE	uk	uk or en
SEARCH_MAX_RESULTS	40	Cap on trips returned per search

Development

npm install
npm run dev        # tsx watch
npm test           # vitest
npm run typecheck

server.json is the MCP registry manifest; eval/evals.xml holds stable-answer evaluations in mcp-builder format.
