Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability64
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1024 tokens (~341/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the Sync My Cycle MCP server?
Sync My Cycle is a hosted endpoint at https://goodturn-mcp.pages.dev/syncmycycle/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_todays_phase Today's cycle phase, with workout and food ideas ~408
Today's cycle phase, with workout and food ideas. Use 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, so suggest a doctor or pharmacist. When `period_may_be_late` is true the say line says the period may be late and suggests checking with a doctor
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Two-letter country code (UK is read as GB). Sets the kit links (US, GB and IE get local Amazon links) and the time zone for today. Pass it for users outside the US. Default from the request. |
| cycle_length | integer | – | Usual days from one period start to the next, 20 to 45. Default 28. |
| date | string | – | Day to ask about, YYYY-MM-DD, a real calendar day. Default today where the user is: from tz, else country, else the request, else UTC. |
| diet | string | – | Comma separated: vegetarian, vegan, pescatarian, halal. Food ideas are filtered to suit. |
| last_period | string | yes | First day of the user's most recent period, YYYY-MM-DD. Must be within the last 120 days. |
| last_period_start | string | – | Older name for last_period, kept for existing callers. Use last_period. |
| period_length | integer | – | Usual days of bleeding, 2 to 10. Default 5. |
| tz | string | – | The user's IANA time zone, for example Europe/London or America/Chicago, so today is the user's today. Optional: country is enough in most places. |
No output schema declared.
No examples provided.
get_week_ahead The days ahead by phase ~385
The days ahead by phase. Use 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
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Two-letter country code (UK is read as GB), used for the time zone of today. Pass it for users outside the US. |
| cycle_length | integer | – | Usual cycle length, 20 to 45. Default 28. |
| date | string | – | First day of the plan, YYYY-MM-DD, a real calendar day. Default today where the user is: from tz, else country, else the request, else UTC. |
| days | integer | – | How many days, a whole number from 1 to 35. Default 7. |
| diet | string | – | Accepted for symmetry with /v1/today; the week view has no food list, so it has no effect here. |
| last_period | string | yes | First day of the user's most recent period, YYYY-MM-DD. Must be within the last 120 days. |
| last_period_start | string | – | Older name for last_period, kept for existing callers. Use last_period. |
| period_length | integer | – | Usual days of bleeding, 2 to 10. Default 5. |
| tz | string | – | The user's IANA time zone, for example Europe/London or America/Chicago, so today is the user's today. Optional: country is enough in most places. |

list_phases What each phase usually feels like, with workout and food ideas ~69
What each phase usually feels like, with workout and food ideas. Use 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

What is the Sync My Cycle MCP server?
Sync My Cycle is an MCP server listed in the public MCP registry as io.github.GoodTurnStudio/syncmycycle. Your likely menstrual cycle phase today and this week, with food and workout ideas. This page covers its hosted endpoint (https://goodturn-mcp.pages.dev/syncmycycle/mcp).
Is the Sync My Cycle MCP server safe to use?
Sync My Cycle scores 69 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Sync My Cycle MCP server expose?
Sync My Cycle exposes 3 tools: get_todays_phase, get_week_ahead, list_phases. Their descriptions and schemas cost roughly 862 tokens of context every time the server is loaded.
Does the Sync My Cycle MCP server require authentication?
No. We connected to Sync My Cycle without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Sync My Cycle MCP server still maintained?
Sync My Cycle is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
