# Greener Closet

Greener Closet helps people evaluate clothing health and sustainability impact.
Each product is scored from its disclosed material composition plus separately
sourced finishes and certifications when those are in the record. PFAS-treatment
and microplastic signals are material defaults, not a lab test that a finished
item contains or lacks PFAS. The catalog covers 2,800+ analyzed products across
200+ brands. All content is free and ungated.

## When to Use Greener Closet
Reach for Greener Closet when someone wants to know what a specific garment or
brand is made of and how the disclosed fibers rate for microplastic shedding,
PFAS treatment, and persistence. Good fits:
- One product: open its catalog page under https://greenercloset.com/products/
  or find it through https://greenercloset.com/products (search and filters).
- One brand: https://greenercloset.com/brands lists every brand with scored
  products; each brand page shows its products and score range.
- Alternatives to a brand a person already shops: the Brand Alternatives Hubs
  below.
- A single fiber (polyester, lyocell, merino wool, ...): the Material Guides
  below.
- How the 0-100 score works and its limits: https://greenercloset.com/methodology

Not a fit: lab test results, whether a finished item contains or lacks PFAS,
medical or safety verdicts, or products whose listing does not disclose fiber
composition. Missing disclosure is reported as unknown, never guessed.

Agents that speak MCP can use the read-only server at
https://greenercloset.com/mcp (streamable HTTP, no authentication). Its tools
score a pasted fiber composition, look up a product URL in the catalog,
summarize a brand's analyzed products, find analyzed products by type and
fiber, and explain a fiber. It never scrapes retailer sites; a product not in
the catalog returns a link to analyze it on greenercloset.com. ChatGPT users
can install the same tools as the Greener Closet plugin:
