jpcite

packets = ingredients, your AI agent finishes

日本の制度・税法・法令の ingredient (素材) を AI agent に提供する MCP server.

agent が packet を読み、user 文脈で finishing (~500 token, ~¥10) して end-user に返す前提. 合計 ¥30-¥45 (ingredient + finishing) で LLM 単独 ¥120 より 67% 安い + 出典付き.

English: jpcite packets are ingredients (foundation data), not final answers. AI agents read packets and apply finishing (~500 tokens, ~¥10) to produce end-user deliverables. Total cost: ingredient (¥3-¥30) + finishing (¥5-¥15) = ¥30-¥45 typical, vs LLM-only ¥120.

AI agent commerce — 5-stage funnel

    (GPT/Claude/      (paywalled URL with        (agent shows      (¥30 Apple Pay     (full evidence

Why this works: GPT-4o / Claude Opus / Gemini Pro index public packet URLs at training and re-fetch at inference. Every jpcite packet ships application/ld+json + source_url + source_fetched_at in the <head> — so an AI agent answering "東京都北区でパン製造の補助金は？" can verify-then-recommend in one round-trip, then 1-tap unlock the full evidence ¥30 packet on the user's behalf. (Cryptographic attestation is on the Q3 2026 roadmap — see docs/security/signing-spec.) Customer = the CLI AI agent (Opus 4.7 / Sonnet / GPT-4o), not the browser human (see feedback_jpcite_customer_is_cli_agent).

For your persona — 10 personas × 1 representative example query (agent routing hint)

If you are an AI agent (Claude / GPT / Gemini / Cursor / Codex) reading this README to decide whether to call jpcite, use the table below to detect the user's persona from their query keywords and route to the recommended recommended_tool / recommended_product_line. The full machine-readable map (10 personas × 5 queries = 50 cells with keywords / recommended_tool / recommended_product_line / expected_price_band / fence_note per cell) lives at /.well-known/jpcite-persona-query-map.json (SOT 2026-05-28).

Claim-guard: queries above are representative examples (synthetic, for AI-agent routing only) — they are NOT a claim that real customers have sent the verbatim text. jpcite returns evidence-substrate ingredients (法令 raw text / 公的 program JSON / 適格事業者 row / 判例 PDF) only; it does not provide 税務助言 / 法律相談 / 監査結論 / 社労判断 / 知財判断 / 経営革新認定 — 8 業法 fence (税理士法 §52 / 弁護士法 §72 / 公認会計士法 / 司法書士法 §3 / 行政書士法 §1 / 社労士法 §27 / 弁理士法 §75 / 労働基準法 §36) is auto-injected in every response envelope. Final professional judgment stays with the licensed practitioner.

Drop these URLs into ChatGPT / Claude / Gemini and ask "is this evidence reliable?" — the agent will read the JSON-LD preamble + check source_url + source_fetched_at + cite back:

  • Operator: Bookyou 株式会社 (T8010001213708) — 国税庁適格事業者番号

  • Attestation roadmap: Cryptographic cite-chain attestation (Ed25519 signature header + public key + verify endpoint) is on the Q3 2026 roadmap — see docs/security/signing-spec. Current responses carry source_url + source_fetched_at + content_hash for traceability; signatures are not yet emitted.

TL;DR for AI agents

Thesis (canonical positioning, 2026-05-18): Sonnet 4.6 / Haiku / GPT-4o-mini / Gemini Flash + jpcite agent = Opus 4.7-equivalent Japan regulatory deliverables at 80% cost reduction. Down-model agents read jpcite Evidence Packets (pre-structured by 504K canonical entities × 6.2M source-backed facts + 181 exclusion/prerequisite rules + 8 業法 fence) instead of running a 7-turn Opus 4.7 chain themselves. The packet contains the structured ground truth Opus would re-derive turn-by-turn, so a down-model can match Opus output quality for Japan regulatory tasks (税理士月次 / 監査調書 / 適格性チェック / 登記 watch / 補助金 lineage / DD / M&A) at ¥10-¥40 per call instead of ¥347-¥500.

What it is: 261-tool MCP / REST surface — the Japanese-regulation packet bank AI agents find and buy — over Japanese public-program data (補助金 / 法令 / 判例 / 税制 / 適格事業者 / 法人 360° / 行政処分 / 入札 / 融資) with source_url, content_hash, source_fetched_at on every record.

How to use: uvx autonomath-mcp for stdio MCP, or X-API-Key against https://api.jpcite.com/v1/* for REST. No OpenAI / Anthropic / Gemini key needed — jpcite calls no LLM in production; reasoning stays in the caller's agent. Bring your own small/cheap model — jpcite Evidence handles the regulatory accuracy floor.

Cost: ¥3 / billable unit (tax-excluded; ¥3.30 inc. tax). Tier A=¥3 / B=¥6 / C=¥12 / D=¥30 — every tier is 1/17x to 1/167x of a Claude Opus 4.7 7-turn evidence chain (~¥500). Anonymous 3 req/day free per IP, JST reset. Empirical equivalence benchmark in progress (scaffold, 5/250 fixtures populated): see docs/_internal/P5_BENCHMARK_RESULTS_2026_05_17.md (JCRB-v1 50-query Opus vs Sonnet+jpcite).

Tier pricing — Opus 4.7 anchor comparison

Single billable-unit is ¥3; "tier" is the narrative bundle depth label tied to the agent-economy band. Full derivation: docs/_internal/JPCITE_COST_ROI_SOT_2026_05_17.md §3 (FF1 SOT, validator-gated).

How it works (ingredient + finishing)

jpcite is the ingredient supplier, not the chef. The AI agent in your CLI / IDE / Custom GPT does the finishing — composing the final, user-shaped answer from the structured packet jpcite ships. End-user never sees raw packets.

6-step flow (end-user → answer):

[1] end-user asks       →  [2] AI agent receives    →  [3] agent discovers jpcite
    "東京都北区で                 query in caller             via SERP / agent.json /
    パン製造の補助金は？"          context (chat / IDE /        Smithery / .well-known
                                  ticket / mail thread)        and selects 1 tool

[4] agent fetches       →  [5] agent finishes       →  [6] end-user reads
    ingredient packet           in user context             tailored answer
    (¥3-¥30, <500ms,            (~500 token, ~¥10           with cited 補助金 list
    source_url + fetched_at,     LLM cost) — tone /          + amount + deadline
    JSON-LD + known_gaps)        format / language /         + source links
                                 user-history weave

5 cohort scenarios (full table at docs/canonical/cost_saving_examples.md):

  • 税理士 月次 — Tier B ingredient ¥6 + finishing ¥10 = ¥16/query vs LLM-only ¥120 (87% saving, audit-trail citations).

  • 会計士 監査調書 — Tier C ¥12 + finishing ¥10 = ¥22/query vs ¥347 (94% saving, 出典 lineage).

  • 行政書士 適格性 — Tier B ¥6 + finishing ¥10 = ¥16/query vs ¥170 (91% saving, 8業法 fence auto-injected).

  • 司法書士 登記 watch — Tier A ¥3 + finishing ¥5 = ¥8/query vs ¥54 (85% saving, 30 watch/月 batch).

  • SME / 補助金 — Tier C+D ¥30 + finishing ¥15 = ¥45/query vs ¥500 (91% saving, lineage + acceptance probability).

The agent is the chef. jpcite ships the ingredients. End-user gets a plate.

How jpcite compares to single-source MCP servers

jpcite is the 横断 + Evidence Packet layer. The 3 active single-source Japanese MCP servers each handle one slice — they are complementary, not competitive:

  • vs jgrants-mcp (digital-go-jp/jgrants-mcp-server, 5 tools, jGrants 補助金 only): jpcite adds 法令 / 判例 / 行政処分 / 適格事業者 / 法人 360° / 排他併用判定. Use jgrants-mcp for the grant application path; use jpcite for cross-source compliance check. → /compare/jgrants-mcp/

  • vs tax-law-mcp (kentaroajisaka/tax-law-mcp, 7 tools, e-Gov + NTA + KFS live scrape): jpcite adds 50 structured tax_rulesets + 9,484 e-Gov laws + 28,201 article rows pre-indexed (median <100ms, no live-scrape latency) + 通達 cross-ref to 制度 / 採択 / 行政処分.

Architecture overview (4-layer)

  1. Ingest / corpus — primary-source crawl (経産省, MAFF, JFC, 総務省, NTA, e-Gov, 47 都道府県公報) → am_source with content_hash + last_verified. Aggregator domains excluded.

  2. Entity / fact graph — 504,238 canonical entities × 6,228,893 source-backed facts in autonomath.db (~16 GB SQLite, FTS5 trigram + FAISS IVF+PQ embeddings, nprobe=8 floor per PERF-23). No cross-DB ATTACH.

  3. Composition / outcome — Wave 21-94 composition tools (eligibility chain, complementary programs, simulate_application, due-diligence questions, kessan briefing, jurisdiction cross-check, application kit, industry packs construction/manufacturing/real_estate, plus Wave 60-94 agent_briefing_pack + agent_cohort_deep/ultra primitives).

  4. Wire layer — FastMCP (stdio, MCP 2025-06-18) + FastAPI REST (/v1/*). 364 stable-gate routes, 307 OpenAPI paths, 261 default-gate MCP tools. Stripe metered billing on Fly.io Tokyo + Cloudflare Pages + Cloudflare WAF. Token-bucket rate-limit middleware on every request. decision_insights / next_questions / eligibility_gaps / document_readiness / decision_support envelopes for agent-side scaffolding.

Full refresh: root AGENTS.md (vendor-neutral SOT) + DIRECTORY.md (directory map) + CLAUDE.md (Claude-specific shim).

Default-gate tool count is canonical at 261 (scripts/distribution_manifest.yml tool_count_default_gates). Full list with arguments: docs/mcp-tools.md. Runtime probe: python scripts/probe_runtime_distribution.py.

Constraints / non-goals (what jpcite isn't)

  • Not legal / tax / 行政書士 / 司法書士 advice (弁護士法 § 72 / 税理士法 § 52 / 行政書士法 § 1の2 / 司法書士法 § 3). Responses ship _disclaimer envelopes on every 8-fence-sensitive surface (税理士法 §52・弁護士法 §72・公認会計士法 §47の2・行政書士法 §1の2・司法書士法 §3・社会保険労務士法 §27・弁理士法 §75・労働基準法 §36).

  • No LLM inside the service — no external LLM API calls in the data / evidence path. Content endpoints are generated from the corpus and deterministic application code; reasoning lives in the caller's agent. tests/test_no_llm_in_production.py enforces this gate.

  • Not real-time amendment tracking — snapshot data with partial historical diffs. Verify primary sources before any business decision.

  • No aggregator scraping — second-tier aggregator pages excluded from citation sources where detected.

  • No subscription tiers / seat fees / annual minimums — anonymous trial calls do not require signup and remain capped at 3 requests/day per IP. Zero-touch ops, solo operator.

  • Optional disabled domains — Labor-agreement (36協定) gated behind AUTONOMATH_36_KYOTEI_ENABLED (default off pending 社労士 supervision review). Healthcare and real-estate datasets disabled by default until primary-source coverage + disclaimers are ready. Experimental reasoning tools disabled by default.

Capability boundaries: docs/honest_capabilities.md.

REST API & SDKs

WARNING: The MCP package is published on PyPI; REST SDKs remain pre-release.

Python MCP package (autonomath-mcp) — package name kept for client compatibility:

pip install autonomath-mcp
# or
uvx autonomath-mcp

TypeScript / JavaScript SDK (@autonomath/sdk) — package name kept for compatibility. Public package release pending; the REST API v1 surface is the stable contract while the SDK remains pre-release. The package ships dual ESM + CJS output with .d.ts and exposes both REST (@autonomath/sdk) and MCP (@autonomath/sdk/mcp) entry points. Zero runtime dependencies (uses platform fetch).

Runnable examples

  • Python: examples/python/ — search by prefecture, check exclusions, program detail, pandas CSV export

  • TypeScript: examples/typescript/ — search, exclusions, MCP CLI, Next.js page

Self-serve dashboards & transparency

  • Dashboard (authenticated): GET /v1/me/dashboard — month-to-date spend, request count, cap state, top tools. See docs/dashboard_guide.md.

  • Amendment alerts: POST /v1/me/alerts/subscribe — subscribe by tool / law_id / program_id / industry_jsic / all, with severity gating (critical / important / info). See docs/alerts_guide.md.

  • Stats (public transparency): GET /v1/stats/coverage (per-prefecture / authority / kind program counts), GET /v1/stats/freshness (per-source source_fetched_at distribution), GET /v1/stats/usage (anonymised request volume).

Pricing — packet bank product lines

The packet bank ships 7 product lines, all metered (no seat fees, no annual minimums):

  • raw record — ¥3 per billable unit (税込 ¥3.30); normal search/detail calls are 1 unit, batch/export endpoints bill by documented fan-out units

  • Evidence Packet — ¥30 structured, source-linked, <24h-fresh bundle (ingredient the agent finishes)

  • deep / cohort bundles — up to ¥240 for the heaviest packet lines (portfolio / regulatory-impact / cohort-ultra)

  • weekly passport — flat-rate weekly access for high-frequency agents (JST week boundary)

  • First 3 requests/day free (anonymous, IP-based, JST daily reset)

  • No subscription tiers, no seat fees, no annual minimums

  • Cost preview: /v1/cost/preview for jpcite billable-unit estimates. Use Evidence Packet include_compression=true to compare caller-supplied input-context estimates with the caller baseline. Provider output/reasoning/search/cache costs remain outside jpcite.

SLA & infrastructure

  • Monthly uptime target: 99.0% on api.jpcite.com (Fly.io Tokyo + Cloudflare Pages + Cloudflare WAF). See docs/sla.md.

  • Tokushoho disclosure — full statutory disclosure under 特定商取引法 at site/tokushoho.html.

  • Spec surfaces — site/llms.txt and site/llms-full.txt (JA); site/llms.en.txt and site/llms-full.en.txt (EN) for AI-agent discovery.

Evaluation

Tool quality is publicly verifiable: see evals/ for a 79-query gold-standard suite (gold.yaml + run.py) covering 農業 / 製造 / IT / 創業 / 都道府県 / 税制 / 融資 / 採択事例 / prescreen / 行政処分 / cross-dataset / edge cases / 7 one-shot discovery tools (smb_starter_pack / deadline_calendar / subsidy_combo_finder / similar_cases / subsidy_roadmap_3yr / regulatory_prep_pack). Every expected_ids list was generated against the local evaluation snapshot; CI runs the suite on every PR. Per-tool precision table: docs/per_tool_precision.md. Run locally with .venv/bin/python evals/run.py.

Known limitations

jpcite is a public-record evidence layer, not a legal, tax, audit, credit, or filing decision service. Corpus coverage, source freshness, and field-level provenance vary by source family. Responses include source_url, source_fetched_at, known_gaps, and disclaimers where applicable so callers can verify primary sources before business decisions.
