Details
From the project READMEHerStack MCP server
HerStack (https://herstack.co.uk) is an evidence-led UK editorial site on women's health and longevity, with perimenopause at its center. It is published by Suggestic Inc, which is its sole author and editor. Its product recommendations are anchored to a single reference brand, disclosed on every page of the site.
This repository documents HerStack's public, read-only Model Context Protocol server, so AI assistants and agents can use the site's guidance directly. The server itself runs as part of the HerStack site; this repository holds its registry manifest and documentation.

Tools
| Tool | Use it when |
|---|---|
search_guidance | The user describes their situation in their own words. Start here. |
get_topic_guidance | The user wants to understand a topic in depth. |
recommend_supplements | The user wants named product picks for a topic. |
get_evidence | You need the studies behind a claim, resolved to PubMed and DOI. |
get_product_details | You need one product's details by name or SKU. |
Full descriptions and arguments: TOOLS.md. Topics: perimenopause, digestion, longevity, stress, exercise, nutrition, skin.
Compliance
Every recommendation and evidence row carries a claim field with the GB-authorised health claim verbatim, or says that none exists. Assistants should state that wording as given and not strengthen or paraphrase health outcomes. Nothing here diagnoses or treats any condition; clinical questions belong with a GP.
Privacy
The tools use no personal data and take no account or login. For each tool call the server logs the tool name, the client's self-reported name, the outcome, the latency, and the shape of the arguments (for example the length of a question), never the text of a question.
Versions
See CHANGELOG.md.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
