An MCP connection for searching Maitabi mountain bus and trekking tours. MCP is a standard way for assistants such as Claude Desktop or Cursor to use external tools.

Use it to list search filters, find tours, view tour details, and check departure calendars.

It puts tour searches and schedules inside supported AI assistants, without requiring terminal commands or direct web requests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00077	$0.01118
Opus 5.5	$0.00031	$0.00447
Sonnet 5.5	$0.00015	$0.00224
Haiku 4.5	$0.00008	$0.00112

Security

Grade A, and why

maitabi-mcp scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 27d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Maitabi MCP Skill

The 7 Maitabi tools below are already available in the MCP client. This skill tells you which tool to call, in what order, and how to read the results.

When to use

Use this skill when the user asks about mountain bus departures (bus.maitabi.jp), lodge packages, guided trekking tours (www.maitabi.jp), departure calendars, prices, live availability, or tour details by course_no.

When NOT to use

Terminal commands or shell scripts → maitabi-cli skill.
Raw HTTP / curl extraction → maitabi-bus-extractor skill.

1. Tools (7)

Mountain bus (`bus.maitabi.jp`)

list_filters — filter dropdown options, lodges, tour counts. Cascading: counts update with other filters. Args: departure (1=Tokyo, 2=Osaka/Kyoto, 3=Nagoya), month 1-12, day, area, style 1-7, return_day 1-5, bus_sheet 1-6, stay1/2/3, course_cd, keyword.
list_district_groups — area/district groups + counts. Same args as list_filters.
search_tours — search bus tours + lodge packages. Same filters plus day as int/list/range string (e.g. '14-16, 20'), page, min_price/max_price (JPY), require_available_seats (drops 満席/受付終了).
get_tour_detail — full itinerary/schedule/pricing by course_no (int or list for batch).

General tours (`www.maitabi.jp`)

search_general_tours — categories travel_type: 1=Domestic Mountain, 2=Domestic Travel, 3=Mountain Bus, 4=Overseas Mountain, 5=Overseas Travel. Args: keyword, year_month (YYYY-MM), day, page, min_price/max_price, require_available_seats, list_order (startDateAsc, saikouStatus, yoyakuStatus, priceAsc, priceDesc), category_nos1-5 (lists).
get_general_tour_detail — itinerary/meals/guide/booking by course_no (int or list).
get_tour_calendar — monthly departure matrix for year/month, optional travel_type.

2. Typical flows

Discover: list_filters (departure+month) → pick area/style IDs.
Search: search_tours (bus) or search_general_tours (trekking) with require_available_seats=true when user wants bookable tours.
Detail: get_tour_detail / get_general_tour_detail with course_no from results.
Calendar: get_tour_calendar for month overview before narrowing days.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
