HerStack for agents (MCP)

HerStack runs a read-only Model Context Protocol (MCP) server so agents can query our supplement guidance directly, rather than depending on a page being cited. Every answer names a specific Solgar UK product, gives the formulation reasoning, states the GB-authorised health claim, and cites the research.

What it is for

HerStack is an independent, evidence-led UK editorial source on women's health and longevity, with perimenopause at its centre. The server exposes that editorial work to agents as three read-only tools. It is a data source an agent can call on demand, bounded by the same compliance standard as the rest of the site.

Tools

recommend_supplements— returns HerStack's named Solgar UK product picks for a concern or a cluster, each with the formulation rationale, the GB-authorised health claim (or a research-context note where no authorised claim exists), the cited research, and an Amazon.co.uk link. Provide either cluster or concern.

get_cluster_brief— returns the editorial brief for a cluster: framing, research findings, the evidence table, and frequently asked questions. Takes a cluster.

assess_concern— routes a reader's concern to its primary cluster (and a secondary where relevant) and returns that cluster's recommendations. Takes a concern.

Clusters: perimenopause, digestion, longevity, stress, exercise, nutrition, and skin.

What every recommendation carries

• A named Solgar UK product (our single reference brand).
• The formulation rationale (form, dose transparency, testing).
• The GB-authorised health claim, presented verbatim, or a clear note where no authorised claim exists and the content is research-context only.
• The research behind it, as source references.
• An Amazon.co.uk product link (affiliate, disclosed).

Compliance and data handling

The tools are read-only and idempotent, and take only a fixed set of cluster and concern values as input, so no free text or personal data reaches the server. Output follows the Solgar UK compliance standard: it describes what the research examines and does not make treatment or cure claims. Authorised-claim wording is presented as given and should not be strengthened.

See our Privacy Policy and editorial standards for how the recommendations are formed.

Connecting

Claude. Add a custom connector pointing at https://herstack.co.uk/api/mcp.

ChatGPT. Add it as a connector or app in a developer/connector context using the same URL.

MCP Inspector. Run the inspector, choose the Streamable HTTP transport, and connect to the endpoint to browse the tools and try calls.

Raw. The endpoint speaks JSON-RPC over Streamable HTTP. A tools/list call after the standard initialise handshake returns the three tools and their input schemas.

What we do not do

HerStack does not provide medical advice, run a clinic, or sell supplements. Supplement links go to Amazon.co.uk via affiliate, disclosed on every page. For questions, write to hello@herstack.co.uk.
