Lowtoxgear — MCP server suite

Two MCP servers for the Lowtoxgear ecosystem. Both live, no-auth, no API key needed — paste a URL into Claude.ai → Settings → Connectors, or call directly via JSON-RPC 2.0 POST.

Both registered under the com.lowtoxgear/* namespace (DNS-verified via lowtoxgear.com) in the Anthropic MCP Registry.

What they do

Lowtoxgear Storefront — shop the catalogue

The Lowtoxgear brand is an Australian low-tox lifestyle e-commerce store spanning four collections:

• Certified Activewear — clothing built without PFAS, fluorocarbons, or synthetic finishes
• Clean Supplements — Australian-sourced supplement products with third-party testing
• GOTS Certified — Global Organic Textile Standard apparel
• Low-Tox Home Products — household items audited for clean ingredients

The storefront MCP exposes the Shopify public catalogue with one brand-specific extension: filter_by_certification lets agents query by tags like GOTS, OEKO-TEX, PFAS-free, etc.

Lowtoxgear Scanner — analyse anything by barcode

The Scanner is an independent Australian ingredient scanner for any consumer product. Live at scan.lowtoxgear.com:

• 21,000+ Australian product pages indexed by barcode (EAN/UPC/JAN)
• 237 source-cited chemical rules — fragrance allergens, EU-banned additives, EDCs, phthalates, PFAS, formaldehyde releasers, parabens, preservatives, and more
• 17 condition-specific flag escalations — MCAS, eczema, PCOS, fertility, pregnancy, fibromyalgia, POTS, IBS, Hashimoto's, fragrance sensitivity, autism, ADHD, asthma, autoimmune, endometriosis, lyme, chronic fatigue
• Six magnet guides of strict-clean shortlists by condition (eczema-safe personal care, mineral-only sunscreens, pregnancy-safe beauty, clean shampoos, etc.)
• No sponsored placement — independent, source-cited

The Scanner MCP is a thin wrapper around the existing scanner backend — it exposes the same data via the MCP JSON-RPC protocol so agents can query it programmatically.

Cross-discovery

Both servers reference each other in their initialize and get_* responses:

• The Storefront's get_policies returns a pointer to the Scanner (for chemical-safety analysis of items found in the catalogue).
• The Scanner's get_resources returns a pointer to the Storefront (for shopping the cleanest-in-cl
