Crystal Suppliers MCP

Crystal Suppliers MCP is a read-only procurement server for KT Crystals. It searches a verified catalog of 104 crystal bracelet SKUs and provides traceable sourcing checklists for loose beads, crystal accessories, and raw crystal materials.

The service does not invent price, MOQ, inventory, lead time, treatment, origin, certification, or shipping claims. Commercial fields remain requires_manual_confirmation.

Install and connect

Run directly from the repository:

{
  "mcpServers": {
    "crystal-suppliers": {
      "command": "node",
      "args": ["/absolute/path/to/crystal-suppliers-mcp/src/index.mjs"]
    }
  }
}

Run the OCI image over stdio:

{
  "mcpServers": {
    "crystal-suppliers": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "ghcr.io/ziyuant222/crystal-suppliers-mcp:0.1.0"
      ]
    }
  }
}

Start Streamable HTTP:

docker run --rm -p 3000:3000 \
  ghcr.io/ziyuant222/crystal-suppliers-mcp:0.1.0 --http

The endpoint is then http://localhost:3000/mcp, with health status at http://localhost:3000/health.

Tools

Tool Purpose
crystal_search_products Search real bracelet SKUs by SKU, name, material, or theme.
crystal_get_product Retrieve one verified bracelet and related catalog products.
crystal_list_materials List normalized materials and verified bracelet SKU counts.
crystal_get_sourcing_guidance Get supplier-verification checks for bracelets, beads, accessories, or raw materials.
crystal_build_procurement_shortlist Keep verified bracelet results separate from adjacent advisory categories.
crystal_prepare_inquiry Validate supplied SKUs and draft an inquiry without sending or storing it.

Coverage contract

  • verified_catalog: grounded in the current 104-SKU bracelet catalog.
  • advisory_only: sourcing guidance only; no verified SKU coverage for the requested category.
  • mixed: verified bracelet candidates plus separately labeled advisory categories.

Inquiry drafting is local and stateless. It does not send email, submit a form, write to a database, or retain buyer details.

Development

npm ci
npm test
npm run start:http

The server supports Node.js 22 or newer and implements MCP over both stdio and stateless Streamable HTTP.
