How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, but returns a challenge with no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0
- Schema blocked by authentication: the endpoint requires auth we don't have to read it. See how to fix → Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Tool Safety0
- Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Capabilities0
- Capabilities blocked by authentication: the endpoint requires auth we don't have to read them. See how to fix → Unverified
Unverified: 6 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm. Claim this server and supply a read-only token to verify it and lift the score.

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
jp_living_costs_lookup Japan daily-life official figures ~496
Japan daily-life official figures, verified against the official pages, by category: minimum-wage (地域別最低賃金 FY2026, hourly, 47 prefectures by romanised key such as tokyo or osaka plus national-weighted-average, each with its own effectiveFrom between 2026-10-01 and 2026-12-02 and the FY2025 amount as previous), health-insurance (協会けんぽ 都道府県単位保険料率 FY2026 by prefecture, employer + employee combined, with the FY2025 rate as previous; long-term-care 介護保険料率 for ages 40–64; child-rearing-levy 子ども・子育て支援金率 from April 2026), pension (kosei-nenkin-rate 厚生年金保険料率, kokumin-nenkin-premium 国民年金保険料 FY2026 and FY2027, kiso-nenkin-full-monthly 老齢基礎年金 満額), employment-insurance (雇用保険料率 FY2026, employee / employer / total per 1,000, three business types), benefits (児童手当 monthly amounts, 出産育児一時金, 高額療養費 ceilings for under-70s before August 2026, August 2026 – July 2027 and from August 2027), holidays (国民の祝日 2027), consumption-tax (10% and 8%, national and local portions), income-tax (基礎控除 table for 2024 to 2028+, 給与所得控除 tables for 2025 and 2026) and resident-tax (均等割 and 森林環境税). Each figure carries its value, unit, the Japanese term, the quoted row from the page, its source URL and effectiveFrom (and effectiveTo where the source states an end); the answer carries verifiedDate, freshness and a citation permalink. No category returns the listing; an unknown category answers covered:false with the nearest keys.

How do I install the io.github.physics-star-cat/databutler-jp-living-costs MCP server?
io.github.physics-star-cat/databutler-jp-living-costs is a hosted endpoint at https://databutler.dev/api/mcp/jp-living-costs, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
