iNutriPlan Supplement Database MCP Server

search_supplements

Search the iHerb product database using a natural-language query, benefit keyword, ingredient name, or brand name. Uses the PostgreSQL GIN full-text search index first (fast, relevance-ranked), then falls back to a broader ILIKE scan if FTS yields no results.

get_supplement_detail

Retrieve complete details for a single iHerb product by its numeric product ID (visible in iHerb URLs, e.g. "72711" from https://www.iherb.com/pr/p/72711). Returns the full supplement facts panel (nutrients, amounts, % daily values), ingredients list, warnings, serving info, and the affiliate purchase link.

search_by_ingredient

Find products that contain a specific ingredient or compound in their ingredients list (e.g. "ashwagandha", "CoQ10", "zinc bisglycinate"). Also returns evidence-graded research context from the ingredient registry when the ingredient is recognised — goals, mechanisms, evidence grade.

list_categories

Return all available iHerb product categories with their URL slugs and live product counts. Use the slug value with get_supplements_by_category to browse products within a specific category.

No parameters.

get_supplements_by_category

List top-rated in-stock products within a specific iHerb category. Use list_categories first to discover valid category slugs.

get_ingredient_info

Look up evidence-graded research context for a supplement ingredient from the curated registry (99 ingredients). Returns canonical name, aliases, health goals, mechanisms of action, evidence grade (Strong / Moderate / Preliminary), research notes, and recommended iHerb search terms.
