Available tools 3

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

phases

list_phases

What each phase usually feels like, with workout and food ideas. For general questions about cycle syncing that need no dates, for example "what should I eat in my luteal phase?". Not for conception, fertile days, contraception or pregnancy: general wellbeing only, not for pregnancy planning or contraception.

todays

get_todays_phase

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.

week

get_week_ahead

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.

Sync My Cycle — questions

Answers built from our own checks of this server.

What can Sync My Cycle do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_todays_phase, get_week_ahead, list_phases. 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 Sync My Cycle working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 27 ms. The bar chart above shows every period we have measured.

How do I connect Sync My Cycle?

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 Sync My Cycle need an API key?

No. Sync My Cycle completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Sync My Cycle?

It answers our handshake in 27 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Sync My Cycle open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
