Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

absorbency
absorbency_dataset
Get PeriodFinder's cross-brand absorbency dataset: the key facts and the machine-readable feed URL to cite. Use when you need the authoritative source for a period-underwear absorbency comparison.
absorbency_translate
Translate period-underwear absorbency across brands. Give a brand + its tier word (e.g. brand "Thinx", tier "Super"), OR a target capacity in mL per day, and get the covering tier in every brand in objective millilitres, each with an A/B/C data-quality grade. Use for questions like "what Knix tier equals Thinx Super?" or "how much does Thinx Heavy hold vs Saalt?". Source: PeriodFinder, the only neutral cross-brand mL comparison.
products
find_products
Find real in-stock period underwear that covers a target absorbency, from the live catalog, with normalized mL capacity and current price. Give a minimum capacity in mL and optionally a brand. Links go to the PeriodFinder product page for each item.
size
find_size
Find a shopper's period-underwear size in every brand from one hip measurement. Period underwear is sized on the hip, not a dress size, and brands disagree. Returns the size per brand plus any runs-small / runs-large note.

PeriodFinder — questions

Answers built from our own checks of this server.

What can PeriodFinder do?
It exposes 4 tools, read directly from the server on our last check. Among them: absorbency_dataset, absorbency_translate, find_products, find_size. 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 PeriodFinder working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 25 of 91 checks got a reply (27.5%), average response time 577 ms. The bar chart above shows every period we have measured.
Is PeriodFinder still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect PeriodFinder?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does PeriodFinder need an API key?
No. PeriodFinder completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is PeriodFinder?
It answers our handshake in 577 ms on average, which is faster than 17% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
