air_choose
Air Choose is a read-only MCP server for monitoring flight prices across multiple airline providers, detecting price drops, and retrieving offers — no booking or ticket ordering capabilities included.
List providers (
list_providers): See available airlines (Kupibilet, Ryanair, SpiceJet, Jetstar Asia), their coverage regions, and requirements.Resolve location codes (
resolve_location): Convert human-readable place names (e.g. "Moscow", "Thailand", "BKK") into each provider's internal airport/city/country codes.Add a watched route (
add_watch): Start monitoring a specific origin–destination–date range, with optional max price and currency filters. An immediate first check runs automatically.Remove a watch (
remove_watch): Stop monitoring a route and clear its price history.List current watches (
list_watches): View all monitored routes, including last check time and offer count.Get offers for a watch (
get_watch_offers): Retrieve the latest known flight offers for a specific watch, sortable by price or date.Poll for new/cheaper offers (
poll_new_offers): Fetch and clear all newly discovered offers (new routes or price drops below the previous best) across all watches since the last poll — the primary way to detect changes.Force an immediate check (
force_check): Trigger an on-demand fare check for a specific watch without waiting for the hourly scheduled cycle.
Allows monitoring of flight fares from Ryanair's API for European routes, including tools for location resolution, route watching, and polling for new offers.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@air_choosestart watching flights from Moscow to Thailand in November"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Read-only MCP server that monitors flight prices across multiple airline providers. An AI agent (Hermes, OpenClaw, Claude, etc.) adds, removes, and inspects watched routes through MCP tools; a background scheduler re-checks every watch hourly and queues new/cheaper offers for the agent to pick up. No ticket ordering — only available flight data.
Features
Multi-provider — Kupibilet (worldwide), Ryanair (Europe), SpiceJet (India), Jetstar Asia (Asia-Pacific)
Flights only — trains and other transport types are filtered out automatically
Smart resolution — turn
"Moscow → Thailand"into provider-specific airport/country codesPrice drop detection — tracks best-ever prices per route, queues notifications when fares drop
MCP-native — works with any MCP-compatible agent host
