Data Butler (databutler.dev)

An agent honeypot: clean, verified UK public data served to AI agents via MCP and REST. Not an SEO play — no GSC ambitions. The customer is an AI assistant answering a human's question; the product is being the source that is *right*, with provenance on every number.

Planned domain: databutler.dev (until purchased/connected, the Vercel default databutler.vercel.app works, but registry listings must NOT be published until the final domain is live — listings bake in URLs).
Status: LIVE (launched 2026-08-31): https://databutler.dev — REST + MCP serving, domain attached, listed on Smithery (drchriseames/databutler-uk-exams, -uk-rates) and the official MCP Registry (io.github.physics-star-cat/databutler-uk-exams, -uk-rates). Tracking LIVE (GA4 property 552213153, verified in realtime; monitored by webmon 🤖 column). PulseMCP will auto-ingest from the official registry. Front door POST /api/mcp — built 2026-09-01 on branch feat/front-door; listing as io.github.physics-star-cat/databutler / Smithery drchriseames/databutler pending deploy.
Born 2026-08-31 out of the agent-API work on whatbreaks.uk (MOT data) and lowriskquotes.com (Monte Carlo) — full history in ../docs/AUDIT_2026-08-30_five-sites.md §3b–3e and ../docs/MONETISATION-DECISION.md.

The model (one brand, many focused servers)

There is no domain authority in MCP registries — discovery is per-listing. So this is NOT one mega-server (tool-list bloat kills those); it is one domain/repo/brand hosting separate, focused MCP endpoints, each listed individually under one namespace, cross-referencing each other:

Front door (2026-09): POST /api/mcp lists the five high-frequency tools directly plus what_changed_since, coverage, catalogue, call. It is still not a mega-server — everything else stays behind call, capped at 9 listed tools by test. Since 2026-10-31 the Vercel firewall answers 403 for every focused server except /api/mcp/facts and /api/mcp/uk-rates: point clients at the front door, whose call runs any tool by name.

The roadmap is ordered by (value to an AI agent) × (likelihood we can build it well). It deliberately includes the maintainer-Claude wishlist — this product is designed with Claude as the end user, by Claude:

#	Vertical (wishlist item it serves)	Endpoint	Status
1	UK rates & thresholds — the "is this still true?" fact-refresh server for the numbers agents misquote most (wishlist #1)	`/api/mcp/uk-rates`	v1 — LIVE
2	UK exams — boards, specs, topic→paper ("is electricity paper 2 AQA"), past-paper index (unique curation edge: maintainer taught)	front door `call` (`/api/mcp/uk-exams`: 403 since 2026-10-31)	v1 — LIVE
3	Provenance checker — "who really runs this domain/package?" (wishlist #2) — live RDAP/npm/PyPI, homoglyph-aware typosquat	front door `call` (`/api/mcp/provenance`: 403 since 2026-10-31)	v1 — LIVE
4	Stats toolkit — exact statistics & probability (Claude's maths pick) — distributions, hypothesis tests, CIs, Bayes, regression; reference-validated	front door `call` (`/api/mcp/stats`: 403 since 2026-10-31)	v1 — LIVE
5	Vehicles hub — UK MOT failure data (live proxy to whatbreaks.uk), UK safety recalls (DVSA, 4,876 recalls since 2016), French recalls (RappelConso, 1,663 fiches), Japanese recalls + owner complaints (MLIT, 75 models); EU Safety Gate stub	front door `call` (`/api/mcp/vehicles`: 403 since 2026-10-31)	v1 — built 2026-10-03
6	Take-home pay — `take_home_pay` for us, uk, ca, au, in, br, de, fr, pl, es: live proxy to the LifeByNumbers salary calculators (same operator), uniform shape (gross/net/deductions annual + monthly, typed breakdown, taxYear, assumptions). Listed at the front door — the highest-frequency money question after rates	front door `call` (`/api/mcp/tax`: 403 since 2026-10-31)	v1 — built 2026-10-03
7	Software end-of-life — "is this version still supported, and until when" for the 14 runtimes/OSes agents are asked about most (Node.js, Python, Ubuntu, Debian, Android, iOS, macOS, Windows, Oracle JDK, Go, Ruby, PHP, PostgreSQL, React): committed monthly snapshot of endoflife.date open data (MIT, 340 cycles), version → cycle resolution, days remaining/since, changelog entries when a cycle reaches EOL or a date moves	front door `call` (`/api/mcp/software-eol`: 403 since 2026-10-31)	v1 — built 2026-10-03
8	Policy rates — `policy_rate`: the three most-asked central-bank rates (BoE Bank Rate, Fed federal funds target range, ECB key rates) as committed, changelogged, source-watched data; the first global step of the "is this still true?" layer (#9, #12). Freshness `due` after 45 days; eight decisions a year each	front door `call` (`/api/mcp/policy-rates`: 403 since 2026-10-31)	v1 — built 2026-10-03
9	US federal rates & thresholds — `us_rates_lookup`: tax year 2026 income-tax schedules and standard deduction, Social Security wage base, Medicare, retirement-plan/IRA, HSA and estate-gift figures read from the IRS revenue procedures, notices and SSA's Federal Register notice, each with the quoted sentence and prior-year value (wishlist #12, "Rates, country #2 = US"); first country after the UK on the "is this still true?" layer	front door `call` (`/api/mcp/us-rates`: 403 since 2026-10-31)	v1 — built 2026-10-03
10	German rates & thresholds — `de_rates_lookup`: Veranlagungszeitraum 2026 Einkommensteuertarif (§ 32a) and Solidaritätszuschlag, Sozialversicherung Beitragsbemessungsgrenzen, Rechengrößen and Beitragssätze, Mindestlohn (2026 and the fixed 2027 step), Geringfügigkeitsgrenze, Kindergeld, Kinderfreibetrag, Pauschbeträge, Entfernungspauschale and the Umsatzsteuer rates (§ 12 UStG), read from the consolidated statutes and the Bundesgesetzblatt with German term + English label, quoted sentence and prior value; country #3 on the "is this still true?" layer	front door `call` (`/api/mcp/de-rates`: 403 since 2026-10-31)	v1 — built 2026-10-03
11	UK vehicle tax (VED) and MOT rules — `uk_vehicle_rules_lookup`: the car-tax and MOT numbers the four car sites' users ask about and that change every 1 April (first-year CO2 bands, standard rate, expensive car supplement incl. the £50,000 EV threshold, 2001–2017 bands, pre-2001 rates, electric-car rules, historic 40-year exemptions, MOT fees/retests/penalties), each with the quoted gov.uk line and its 2025-26 value; calendar-driven refresh	front door `call` (`/api/mcp/uk-vehicle-rules`: 403 since 2026-10-31)	v1 — built 2026-10-04
12	UK exam dates and spec changes — results days, the summer 2027 timetable (JCQ window + the most-asked papers at AQA, Pearson Edexcel, Cambridge OCR and WJEC/Eduqas, all final), entry deadlines with each board's late-fee dates, Scotland's results day, announced spec changes; every date quoted from the JCQ/board/regulator document with the summer-2026 date as previous	front door `call` (`/api/mcp/uk-exam-dates`: 403 since 2026-10-31)	v1 — built 2026-10-04
13	Calendar facts — the boring dates a training cutoff hides: public holidays for the UK (3 nations), US federal, Germany (16 Länder) and France (2 zones) from the official lists; tax-year starts/ends for 9 countries with the statute quoted; daylight-saving rules and computed switch dates for 6 countries — 2026–2028, monthly snapshot, changelog when a year is published or a holiday moves	front door `call` (`/api/mcp/calendar`: 403 since 2026-10-31)	v1 — built 2026-10-04
14	UK government services — `uk_gov_process`: the gov.uk services assistants get wrong after a fee or rule change (passport fees UK/overseas, ETA fee and enforcement, driving licence renewal, SORN, voter registration, birth/death registration, Blue Badge, Self Assessment and Making Tax Digital, NI number, Universal Credit, EU Settlement Scheme, BRP → eVisa), each with the official start URL, the quoted gov.uk sentence and dated changes	front door `call` (`/api/mcp/uk-gov-process`: 403 since 2026-10-31)	v1 — built 2026-10-04
15	Japan vehicle statutory costs — `jp_vehicle_costs_lookup`: the 法定費用 of a 車検 and the annual car taxes for the shakendata.com audience (自動車重量税 2026-05 – 2028-04 table and age rules, エコカー減税 bands, 自賠責 before and from 2026-11-01 as separate keys, 継続検査 fees from 2026-04-01 with the old amounts, 自動車税 by displacement, 軽自動車税), each with the Japanese term and the quoted official row; first non-Western country and the `jp` facts namespace	front door `call` (`/api/mcp/jp-vehicle-costs`: 403 since 2026-10-31)	v1 — built 2026-10-24
16	Japan daily-life official figures — `jp_living_costs_lookup`: the figures a resident or employer in Japan looks up (地域別最低賃金 FY2026 for all 47 prefectures with their staggered 発効日 and FY2025 amounts, 協会けんぽ rates by prefecture with 介護 and 子ども・子育て支援金, 厚生年金 / 国民年金, 雇用保険料率, 児童手当, 出産育児一時金, 高額療養費 through the 2026 and 2027 revisions, 2027 祝日, 消費税, 基礎控除 / 給与所得控除, 住民税均等割), each with the Japanese term and the quoted official row; prefecture figures are individual facts (`jp/minimum-wage/tokyo`)	front door `call` (`/api/mcp/jp-living-costs`: 403 since 2026-10-31)	v1 — built 2026-10-24

Planned, parked and out of scope (hand-maintained — these are not area modules):

#	Vertical (wishlist item it serves)	Endpoint	Status
4	Local-services resolver — postcode → council → services/MP (wishlist #3)	`/api/mcp/uk-councils`	phase 2
5	Bin collection pilot (5–10 large councils, feasibility-gated)	—	phase 2b
3c	Front door — single `POST /api/mcp` hub: direct high-frequency tools + `what_changed_since` (changelog vs. your training cutoff), `coverage`, `catalogue`/`call`; freshness + citation permalink on every response; weekly gov.uk source watcher (spec: `docs/superpowers/specs/2026-09-01-front-door-design.md`)	`/api/mcp`	built — deploy pending
9	Drift facts (global) — facts that move on a calendar and agents misquote: tax-year boundaries by country, public holidays, DST transitions, currency/country codes, headline VAT/sales-tax rates. Cheap to curate, low rot, feeds `what_changed_since`	`/api/mcp/drift`	after front door
10	Volatility tool — `volatility(topic)`: how often a class of fact changes and when it last did, so an agent knows whether to trust memory at all. Curated table, no per-country data; Claude's own top pick for the global layer	front door tool	after front door
11	Provenance, widened — crates.io, RubyGems, Go modules, Docker Hub, GitHub Actions, browser extensions; then MCP-server provenance (cross-check a registry listing's claimed domain, repo and publisher — the hub that vets other hubs)	`/api/mcp/provenance`	after front door
12c	Rates, further countries — AU/CA/IN sites 403 automated fetches (browser-only curation); US and Germany are built (roadmap above)	`/api/ /rates`	after the source watcher proves the annual loop on us-rates/de-rates

| 13 | Exams, global boards — IB and AP: same topic→paper query stream, same teaching moat
