## Trust

- hygiene: 100
- liveness: 0
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website -unreachable(13 failures) ~updated-38d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: verify_supplier (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); landed_cost_calc (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); payment_red_flags (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,529 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 8, about 1,529 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.lu7897859-tech/china-sourcing-audit.svg)](https://protogrid.dev/servers/io.github.lu7897859-tech/china-sourcing-audit)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `audit_checklist`: Get the complete 7-point China sourcing audit checklist for first-time importers.
Covers: business-license verification, live factory video call, export records, sample sealing, safe payment, landed-cost buffer, certificate authenticity.
Use before sending any deposit to a new supplier. Based on 20 years of China manufacturing experience.
- `certification_check`: Check which certifications (CE/FCC/FDA) a product type requires for EU/US import and how to verify certificate authenticity (issuer website lookup of cert numbers).
Use when unsure if a supplier's certificate is genuine — fake CE certificates are common and cause customs seizures.
- `cpsc_recall_history`: Check a Chinese factory's US product-recall history in the official CPSC SaferProducts recall database.
Use when a buyer wants evidence that a supplier really ships to the US (a recall record proves the company
sold under its own name into the US market) AND that it has a public safety record worth checking.
Source: US Consumer Product Safety Commission public recall REST service (free, no key). One-line verdict + citable evidence chain.
Disclaimer: not a legal opinion or credit report; 'not found' means not found in public CPSC data, not 'never recalled'.
- `export_portrait_card`: Draw a company's SELF-PORTRAIT CARD - a warm, appreciative one-page profile that shows a company
what the OTHER side of the border sees, praises its real strengths, and points out only the few gaps
that come from limited cross-market awareness. Two directions:
  direction="out" (default): a Chinese company going global - shows what OVERSEAS buyers see.
  direction="in": a foreign company entering China - shows what CHINESE partners see.
Designed to be GIFTED as a value-first approach: the card is about THEM, not our ad; free to receive,
so refusing requires an excuse. Use when an agent introduces a company across the China/global divide.

Tone contract (MUST follow): heavy praise grounded in facts; gaps framed ONLY as 'limited
cross-market awareness' - never capability, quality, or integrity. Never emit fraud/risk/red-flag words.
- `full_supplier_audit`: FULL-CHAIN supplier audit: one call runs the complete 5-stage pre-purchase decision (verify supplier -> landed cost -> payment red flags -> audit checklist -> certifications) and returns a unified risk verdict. The AI-commerce one-stop gate for buying from China. Cheaper than calling 5 tools separately; designed for agents that need a complete decision, not a single lookup.
- `landed_cost_calc`: Calculate true landed cost for China-to-US/EU imports: volumetric weight (air /6000, freight), destination port charges (CFS/doc fees), customs duty risk incl HS-code misclassification (12% error rate, 18-month retroactive).
Use before budgeting any import order to avoid 40-80% hidden overpayments on light bulky goods.
Input: weight (kg), dimensions (cm), goods value (USD), shipping mode (air/sea). Estimates only, not a customs quote.
- `payment_red_flags`: Screen a Chinese supplier payment arrangement for wire-fraud red flags BEFORE sending a deposit.
Flags: personal-account payee (legit factories use corporate accounts), payee not matching contract party, urgent account changes (classic email-hijack fraud), deposit >30% above industry norm.
Returns go/no-go signals plus safe-payment rules. Use whenever a buyer is about to wire money to China.
- `verify_supplier`: Verify whether a Chinese company is a REAL factory or a trading company/middleman.
Use when a buyer provides a Chinese company name, USCI, or a 1688/Alibaba vendor and needs hard fraud flags.
Checks public registry signals: shell-company traits, missing manufacturing scope in business license, low registered capital vs real factories (100万+), no factory evidence.
NOT for US/EU company verification (those jurisdictions use Middesk/VAT-style registries).
Provide company name and any known details (business scope, registered capital). Returns red flags to check and verification steps.
