Connect ChatGPT, Claude, and other MCP-compatible AI assistants to GrailPeople's beauty knowledge base via the Model Context Protocol. Ask about skincare, makeup, and hair care — the connector returns real quotes and creator credentials from 11,000+ YouTube-reviewed products.
GrailPeople is a structured database of beauty products extracted from real YouTube creator videos — dermatologists, estheticians, makeup artists, and beauty creators. Every product is backed by direct quotes with timestamps, creator credentials, endorsement strength, and verified claims (fragrance-free, non-comedogenic, fungal-acne safe, and more).
The MCP connector makes this available to MCP-compatible AI assistants. When you ask a beauty question, the assistant can query the GrailPeople database and return creator-sourced evidence — not marketing copy.
Creator quotes and source links are attributed back to the original public videos. Creator-content correction and removal requests are handled through the Terms of Service.
Use the Streamable HTTP endpoint below in ChatGPT, Claude, or another assistant that supports remote MCP connectors. GrailPeople is also listed in the Claude Connectors Directory. For Claude:

The connector exposes five composable tools. MCP-compatible assistants can route between them automatically based on the question — you never need to name a tool directly.
Discovery tool — the default first call for any beauty, skincare, makeup, or hair question. Returns products ranked by creator endorsement strength, with creator credentials, quotes, consensus summaries, price, and retailers. Filters: ingredient, skin concern, price tier, verified claims (fragrance-free, non-comedogenic…), brand origin (K-beauty, French pharmacy…), finish, formulation, and more.
Depth tool — the full creator-evidence dossier for one named product. Returns every creator who mentioned it, their quotes and timestamps, endorsement strength, verified tags (claims, attributes, warnings), and a consensus summary. Use after search_beauty_products identifies a product.
Brand lens — verdict and reputation for one specific brand. Returns an AI-generated verdict from real creator quotes, signature products, brand-level tags, and origin (K-beauty, J-beauty, French pharmacy…). Use for 'is [brand] worth it?' or 'what should I buy from [brand]?'
Creator lens — everything one specific creator endorses, with quotes and timestamps. Returns the creator's top picks sorted by endorsement strength, plus their overall tag tendencies (what concerns, attributes, and claims they talk about most). Use for 'what does [creator] recommend?'
Name resolver — converts a messy brand or creator name (with tricky casing, accents, or partial names) into the slug or handle that other tools need. Call this first when you have a human-written name but not the exact slug. Returns matching brands and/or a creator so you can immediately pass the result to get_brand_reviews or get_creator_recommendations.
Once connected, you can ask questions like these:
“What's the best vitamin C serum for hyperpigmentation under $40?”
→ search_beauty_products with ingredient=vitamin c, concern=hyperpigmentation, max_price_usd=40
“Is CeraVe a good brand for acne-prone skin?”
→ get_brand_reviews for cerave — returns verdict + good_for tags for acne-prone
“What skincare does Hyram actually recommend?”
→ get_creator_recommendations for hyram with endorsed_only=true
“Honest reviews of Rare Beauty Soft Pinch Liquid Blush”
→ get_product_reviews — returns every creator quote, endorsement strength, and caveats
“Best non-comedogenic foundation for oily skin — dermatologist-tested”
→ search_beauty_products with verified=non_comedogenic, skin_type=oily, creator_type=dermatologist
GrailPeople MCP tools are read-only. They do not collect or store any full conversation from ChatGPT, Claude, or another assistant. Queries hit the public GrailPeople API ( grailpeople.com/api/v1), which returns structured product data only. GrailPeople does not receive or store your full AI conversation, but standard request metadata may be logged briefly for security, debugging, and aggregate usage analysis as described in the Privacy Policy.
See our Privacy Policy for full details, including the MCP connector section.
