Discovery-only supplier data is easy to come by; what is scarce is a second, independently measured number next to the claim, and that is what these records carry. The `verified_dims` score is the field to build on — an agent can be told to skip anything below a threshold rather than treating every listing as equally solid. Pricing is per-day request quota, so plan bulk comparison work around the tier you are on.
A hosted MCP server over a Chinese apparel supply-chain dataset: roughly 3,000 manufacturers, 350+ lab-tested fabrics and 170+ industrial clusters across 31 provinces. Every supplier and fabric record carries both what the supplier declared and what was independently measured, plus a `verified_dims` score showing how many of eight verification dimensions have been checked.
- Three search tools that filter without a lookup table — `search_suppliers` by province, type, capacity, compliance status and quality score; `search_fabrics` by category, weight in gsm, composition and price; `search_clusters` by province, specialization and scale
- Full records on demand: `get_supplier_detail` and `get_fabric_detail` return the complete profile including lab measurements, certifications and market access
- Cross-references that answer follow-up questions in one call — `get_supplier_fabrics`, `get_fabric_suppliers`, `get_cluster_suppliers`, plus `compare_suppliers` and `compare_clusters` for side-by-side reads
- `detect_discrepancy`, which surfaces exactly where a declared value diverges from the tested one, sorted by the size of the gap
- Sourcing help rather than raw rows: `recommend_suppliers`, `find_alternatives`, `check_compliance` against a target export market, `estimate_cost` and `analyze_market`
- A slim mode of three tools — `search_suppliers`, `search_fabrics` and `get_stats` — for agents on a tight context budget
A free API key from the vendor's apply page, sent as a bearer token. The primary route is the hosted endpoint `https://api.meacheal.ai/mcp` over Streamable HTTP, pasted into any client's MCP config with an `Authorization` header; `claude mcp add --transport http` does the same in one command. An npm launcher also exists — `npx mrc-data` with `MRC_API_KEY` set — and the same data is available over a REST API with an OpenAPI 3.1 spec. The free tier allows 100 requests per day.
One command plus a key — MRC_API_KEY=your_key npx mrc-data, then supply credentials
