Greener Closet does not always answer
Over the last week it answered 12.1% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

alternatives
find_alternatives
Use this when the user wants clothing with specific fiber content or an alternative to a brand, for example "leggings like Lululemon without polyester", "Vuori dupes without synthetic fabric", "natural fiber underwear for women", "linen shirts for men with no synthetics" or "polyester-free socks". For a PFAS-free request it can find clothing with no synthetic fibers, but fiber content is not a PFAS test. Returns products Greener Closet has analyzed, highest score first, with their disclosed fiber breakdown. Fiber exclusions only count products whose full composition is disclosed. It doesn't filter by price. Do not use this to check one product or brand (use check_product or check_brand).
brand
check_brand
Use this when the user asks about a clothing brand's materials or sustainability, for example "is Vuori sustainable", "is Vuori non-toxic", "does Vuori use PFAS", "is Lululemon mostly polyester" or "what are Quince clothes made of". Returns how the brand's products that Greener Closet has analyzed score, how many contain synthetic fibers, and any sourced claims on file. It never rates the company itself, and it can't say whether a brand uses PFAS finishes. Do not use this for one product (use check_product) or to find other brands (use find_alternatives).
explain
explain_fiber
Use this when the user asks what a clothing fiber is or whether it's natural, synthetic or a concern to wear, for example "is modal a natural fiber", "is polyester bad for you", "what is Tencel", "is rayon a natural fiber", "is spandex as bad as polyester" or "what is regenerated cellulose". Returns Greener Closet's reviewed guide with sources when one exists, and says plainly when it has only limited information. Do not use this to score a whole garment label (use check_fabric_label).
fabric
check_fabric_label
Use this when the user gives a garment's fiber composition or care-label text (for example "60% cotton, 40% polyester" or "100% merino wool") and asks whether it's good, sustainable, synthetic, plastic-based or a better choice than another label, for example "my shirt label says 52% organic cotton, 48% recycled polyester. is that good?" or "95% cotton 5% elastane vs 60% cotton 40% polyester, which is better". To compare labels, call it once per label. Returns Greener Closet's 0-100 score, the synthetic share and the main concerns. If the percentages don't add up to 100, it reports the gap instead of a score. Do not use this for a product URL (use check_product) or for a general question about one fiber (use explain_fiber).
product
check_product
Use this when the user shares a link to a clothing product page and asks what it's made of, whether it contains polyester or other synthetics, whether it's 100% cotton, or how sustainable it is, for example "what is this shirt made of? <link>". Returns Greener Closet's stored fiber breakdown and score when the product is in its catalog. Otherwise it returns a link where the user can analyze the product on greenercloset.com. Do not use this for pasted label text (use check_fabric_label) or for a product described without a URL.

Greener Closet — questions
Answers built from our own checks of this server.
What can Greener Closet do?
It exposes 5 tools, read directly from the server on our last check. Among them: check_brand, check_fabric_label, check_product, explain_fiber, find_alternatives. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Greener Closet working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 3 of 92 checks got a reply (3.3%), average response time 297 ms. The bar chart above shows every period we have measured.
The registry lists Greener Closet as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Greener Closet?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Greener Closet need an API key?
No. Greener Closet completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Greener Closet?
It answers our handshake in 297 ms on average, which is faster than 48% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
