Overview

AI-generated overview

Remote MCP server that tells an assistant the user's likely menstrual cycle phase today and this week, with food and workout ideas.

What you can do
  • Get today's likely cycle phase with workout and food ideas from a last-period start date
  • Plan the week ahead day by day with likely phase, workout focus, intensity and food focus
  • Look up what each phase usually feels like, with general workout and food suggestions
When to use it
Useful when someone wants everyday cycle-syncing guidance: what phase they are in, what to train or eat today, or how to plan training and meals for the coming week. Also fine for general questions about what a phase is typically like.
Requirements
A remote streamable HTTP endpoint; no sign-in, API key or environment variables are declared. The phase tools need the first day of the last period as input.
Before you install
It is general wellbeing guidance, not medical advice, and the tools state they are not for conception, fertile days, ovulation timing, contraception or pregnancy. The last-period date is sent to the remote service; the README says nothing about the user is stored. All tools are described as read-only.

Installation

In SourceWeft

  1. Open Sync My Cycle 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.GoodTurnStudio%2Fsyncmycycle/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

Other MCP clients

Add this to your client's mcpServers config.

How it works

  • build.py reads each product's live openapi.json and writes products.js: one tool per GET operation, named from its operationId, with inputs from its parameters. Descriptions are tidied into plain tool descriptions.
  • worker.mjs is the MCP server: initialize, tools/list and tools/call, which calls the product's own API and returns its answer. Answers with a say field carry a ready-made summary.
  • servers.json lists every server for the official MCP Registry (as io.github.GoodTurnStudio/<slug>). The Publish to the MCP Registry workflow logs in with GitHub OIDC and runs publish.py; publish.ps1 does the same from Windows.

Build and test

npm installnpm run build          # python3 build.py, then bundle to deploy/_worker.jsnpm test               # every product through the worker, against the live APIsnpm run test:live      # every tool through the deployed servers with the MCP SDK client

Deploy deploy/ as a Cloudflare Pages project in advanced mode (_worker.js).

Licence

MIT for this code. Each product's API, data and answers belong to that product and are served under its own terms, linked from its page at https://goodturn-mcp.pages.dev/<slug>.

get_todays_phase

Today's cycle phase, with workout and food ideas

Today's cycle phase, with workout and food ideas. For when the user asks what phase they are in, what workout or food suits them today, or why their energy is up or down, for example "what phase am I in, my last period started September 12th" or "what should I train today?". Needs the first day of their last period. Not for getting pregnant, fertile days, ovulation timing, contraception or pregnancy: this is general wellbeing only, not for pregnancy planning or contraception, and a doctor or pharmacist is the right person for those. When `period_may_be_late` is true the say line says the period may be late and suggests checking with a doctor.

get_week_ahead

The days ahead by phase

The days ahead by phase. For when the user wants to plan training or meals for the week, for example "plan my training this week around my cycle". Returns each day's likely phase, workout focus, intensity and food focus. Not for getting pregnant, fertile days, ovulation timing, contraception or pregnancy: this is general wellbeing only, not for pregnancy planning or contraception, and it is not a fertility calendar. When `period_may_be_late` is true, `days` is empty and the say line suggests checking with a doctor.

100% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
