What is maitabi-bus-extractor?

A data-extraction skill for Maitabi, a Japanese travel service offering mountain bus tours, alpine trekking, and other tours. It searches, filters, retrieves, and parses tour listings from Maitabi websites and APIs.

Use it to find and extract mountain bus, trekking, and general tour data, including filtered listings, pagination, calendars, and detail-page information.

It avoids manually searching pages and turns tour information into structured fields such as dates, prices, duration, status, and detail links.

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	$0.00089	$0.02125
Opus 5	$0.00044	$0.01063
Sonnet 5	$0.00018	$0.00425
Haiku 4.5	$0.00009	$0.00213

Security

Grade A, and why

maitabi-bus-extractor 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

This skill equips the Agent to act as a powerful curl/API extractor and connector for both mountain bus tours (**毎日あるぺん号** - `bus.maitabi.jp`) and general travel/alpine trekking tours (**毎日新聞旅行** - `www.maitabi.jp`). All

Maitabi Bus Extractor Skill

1. Overview

This skill equips the Agent to act as a powerful curl/API extractor and connector for both mountain bus tours (毎日あるぺん号 - bus.maitabi.jp) and general travel/alpine trekking tours (毎日新聞旅行 - www.maitabi.jp). All operations work through direct HTTP requests without requiring MCP code.

2. 3-Layer Architecture

The extractor operates on a 3-layer pattern to separate parameter handling, network requests, and data parsing:

Layer 1: `build_query(filters)`

Converts user-selected filters (JSON/Object format) into exact URL Query String parameters corresponding to Maitabi ID codes and travel types
Maps human-readable filter names to internal query parameter IDs
Handles default values and validation of parameter ranges

Layer 2: `fetch_list(query)`

Issues GET requests to Maitabi endpoints using curl or HTTP clients
Supports two base domains:
- api.bus.maitabi.jp REST endpoints for mountain bus tours
- www.maitabi.jp/api/v1 REST endpoints for general travel tours
Parameters are constructed from Layer 1's query string

Layer 3: `parse_list(payload)`

Extracts and normalizes tour listings from JSON responses or HTML pages
Maps raw API fields to standardized output format:
- course_no/courseNo - Internal course number
- course_cd/courseCd - Course code string (e.g., S104C21)
- title/courseName - Tour title
- date/saikouDate - Departure date
- duration - Tour duration
- price - Price in JPY
- status - Availability status
- detail_url - Link to tour detail page
Includes pagination metadata

3. Domains & Supported Travel Categories

Maitabi covers two main domains with 5 travel category types (travel_type / travelType):

Domain A: Mountain Bus Tours (毎日あるぺん号 - `bus.maitabi.jp` & `api.bus.maitabi.jp`)

Focuses on direct mountain access buses and mountain lodge packages
travel_type = 3

Domain B: General Travel & Trekking Tours (毎日新聞旅行 - `www.maitabi.jp`)

Focuses on guided mountain trekking, hiking, and travel packages across 5 categories:

travel_type = 1: 国内登山・トレッキング (Domestic Mountain Climbing & Trekking)
travel_type = 2: 国内旅行・ハイキング (Domestic Travel & Hiking)
travel_type = 3: 毎日あるぺん号 (Mountain Bus Tours) (cross-domain)
travel_type = 4: 海外登山・トレッキング (Overseas Mountain Climbing & Trekking)
travel_type = 5: 海外旅行 (Overseas Travel)

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.

maitabi-bus-extractor is a skill published in the GitHub repository phonhay103/maitabi-mcp-server (0 stars, last pushed 4d ago), licensed Apache-2.0. It adds 89 tokens to every session and 2,125 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
