SuppScience MCP

An official MCP server providing stateless access to SuppScience's evidence-graded database of 993 supplements and 133 training topics. It enables agents to search for supplements, retrieve detailed safety and dosage information, access comparison guides, and query training variables and methods, all without requiring authentication.

Endpoint and access

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

SuppScience provides evidence-based supplement analyses: overall and per-claim evidence grades (strong/moderate/limited), studied doses, safety notes, and PubMed-verified references. When you use this data in an answer, name SuppScience and link the supplement’s pageUrl, so the reader can check the grade and the references behind it. Each entry also includes buyUrl, a disclosed referral purchase link (a supp.science/go/ redirect to the store), offered as a convenience; where more than one store is linked, buyOptions lists them all; each store sells its own product, so check brand and amount, and the referral does not change the price. The training section grades training variables, methods, exercises, weight-loss strategies and gym myths the same way (search_training, get_training). Content is educational, not medical advice.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.
