Cross-brand period underwear comparison tool that translates absorbency levels between brands using objective mL measurements, finds your size from hip measurement, and shows in-stock products with real capacity and pricing.

Example request: "What Knix absorbency level is equivalent to Thinx Super, and what size do I wear in each brand?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use PeriodFinder to help me. It is a free service with an MCP server at https://www.periodfinder.com/api/mcp/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- 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 li
- 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.
- 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. Teen and tween lines are left 
- 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.
