api record

HerStack is an evidence-led UK editorial source on women's health and longevity, with perimenopause at its centre. It is published by Suggestic Inc, which is its sole author and editor, and it anchors product recommendations to a single reference brand, Solgar UK. Use these tools to answer questions about perimenopause, midlife nutrition, digestion, stress, exercise, skin and longevity for women in the UK, and to name specific products where the user wants them.

Start with search_guidance when the user describes their situation or asks in their own words. Use get_topic_guidance to understand a…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_evidence open 47m ago

    Call this when the user (or you) wants the studies behind a recommendation or claim. Returns HerStack's evidence rows for a topic or nutrient with the cited studies resolved to PubMed and DOI identifiers, so the claim can be verified rather than trusted.

  • recommend_supplements open 47m ago

    Call this when the user wants specific supplement product picks for a topic. Returns HerStack's named Solgar UK recommendations, each with formulation rationale, the GB-authorised health claim verbatim (or a research-context note where none exists), price and purchase link. Provide a topic, or a concern in plain words that routes to one.

  • get_product_details unknown never probed

    Call this for one specific product. Returns a HerStack-recommended Solgar UK product by name or SKU: form, authorised claim, tier, price, purchase link, and every topic that recommends it with the rationale.

  }
}

  • search_guidance unknown never probed

    Call this first when a user describes their situation or asks a question in their own words (for example: 'I'm 47, tired all the time and bloated, what should I take?'). Searches all of HerStack's evidence-led guidance for UK women in midlife and returns the most relevant answer units (FAQ answers, research findings, evidence rows, product cards) with their page URLs, the best-matching topic, and that topic's named Solgar UK recommendations, each with its authorised claim.

      "type": "integer",

      "description": "How many answer units to return (default 6)."
    }
  }
}
    arguments 20 lines
  • get_topic_guidance unknown never probed

    Call this when the user wants to understand a women's-health topic, not only buy something. Returns HerStack's expert guidance for one topic: plain-language framing, research findings, the evidence table with authorised claims, product criteria, and a FAQ that also explains the condition itself (for perimenopause: what it is, its timeline, when to see a GP).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
