What is the Supplement MCP server?

If you already use Supplement, the supplement mcp server is the piece that lets your assistant work with it directly. Evidence-based supplement guidance: clinical doses, form comparisons, interactions, cost-per-dose.

What the server does

Evidence-based supplement recommendation MCP server. 19 supplements, 40+ conditions, medication interaction checking, form quality classification. Data sourced from NIH DSLD, PubMed, NSF, and USP.

Installation

The server ships on npm as supplement-advisor-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • recommend_supplement — Get ranked supplement recommendations for a condition with clinical evidence, dosing, cost-per-dose, and purchase links
  • compare_forms — Compare different forms of a supplement (e.g., magnesium glycinate vs citrate vs oxide) with absorption data and warnings
  • check_interactions — Check if medications deplete nutrients — covers statins, metformin, PPIs, birth control, and more
  • get_dosage — Get evidence-based dosage recommendations by condition, with clinical trial references and timing guidance
  • classify_form — Paste any product name or ingredient list and get a quality verdict on the supplement form used

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Supplement's toolset — recommend_supplement, compare_forms, check_interactions and 2 more — is a fair guide to whether it matches your workflow. It is maintained by com.verifiedsupplementdata; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Supplement's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Frequently asked questions

Instead of copying data back and forth by hand, the assistant works with Supplement directly.
