What is maitabi-mcp-server AGENTS.md?

Repository instructions for keeping the Maitabi MCP server and its standalone skill in sync. They document how travel and mountain-bus filters are converted into requests and standardized results.

Use them when modifying Maitabi's query building, API requests, response parsing, travel types, or mountain-bus filters.

They reduce the risk that the server and skill accept different inputs or produce inconsistent results after changes.

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	$0.01255	$0.01255
Opus 5	$0.00628	$0.00628
Sonnet 5	$0.00251	$0.00251
Haiku 4.5	$0.00126	$0.00126

Security

Grade A, and why

maitabi-mcp-server AGENTS.md scanned grade A with 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Maitabi MCP ↔ Skill Sync Guide

Purpose: Keep MCP server (src/) and standalone skill (skills/maitabi-bus-extractor/) in sync.

Architecture (Both Layers Match)

Layer 1: build_query(filters)  →  URL query string
Layer 2: fetch_list(query)     →  HTTP GET to api.bus.maitabi.jp / www.maitabi.jp/api/v1
Layer 3: parse_list(payload)   →  Standardized JSON (course_no, course_cd, title, date, price, status, detail_url)

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.
