Overview

AI-generated overview

Lets an assistant compare period underwear across brands by real absorbency in milliliters and translate sizing between brands.

What you can do
Provides neutral cross-brand comparison of period underwear. It reports absorbency in real milliliters rather than vague labels, and translates sizes from one brand to another. The manifest lists no individual tools, so the exact operations are not documented.
When to use it
Useful when someone is choosing period underwear and wants absorbency figures that are comparable across brands, or needs help mapping their size in one brand to another. Less relevant for general shopping or health questions outside that product category.
Requirements
A remote MCP endpoint at reached over streamable HTTP. No package, runtime, account, API key, environment variable, or header is declared. Network access to that endpoint is required.
Before you install
The description does not state whether the assistant can only read comparisons or also take actions such as saving preferences or clicking through to a retailer. No authentication is declared, so no credentials are requested, but any data sent to the remote endpoint leaves the user's machine. Confirm current product details with the manufacturer before relying on them.

Installation

In SourceWeft

  1. Open PeriodFinder in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.fenrici1%2Fperiodfinder/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

absorbency_translate

Translate absorbency across brands

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.

Parameterstierbrandml_per_day

find_size

Find your size in every brand

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.

Parametership_cmhip_inches

find_products

Find in-stock products by absorbency

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 out unless teen is true.

Parametersteenbrandlimitml_min

absorbency_dataset

Cite the 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.

Takes no parameters.
