Clarity

MCP Queen grade

Condition-aware ingredient & product safety intelligence for AI agents. Every answer carries a verdict, an evidence tier (Gold / Silver / Bronze), and a citation — curated against authoritative sources (LactMed, InfantRisk, PubMed, DSLD, DermNet, EU CosIng) by Health AI (Dr. Olga Lavinda, PhD).

Hosted MCP server — no install, no key. Endpoint: https://mcp.healthai.com (Streamable HTTP, JSON-RPC 2.0). Published to the official MCP Registry as com.healthai/clarity (domain-verified namespace).

Use it

Claude Code:

claude mcp add --transport http clarity https://mcp.healthai.com

Claude Desktop / Cursor / any client with native remote MCP — add to the config's mcpServers:

{
  "mcpServers": {
    "clarity": {
      "type": "streamable-http",
      "url": "https://mcp.healthai.com"
    }
  }
}

For older clients without native remote support, bridge with mcp-remote: "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.healthai.com"].

Tools (9)

Tool	What it answers
check_ingredient	Verdict + evidence tier + citation for a cosmetic/food/supplement ingredient, under a condition lens
strain_lookup	Verdict, tier, PMID citation and safety flags for a cannabis or mushroom species/strain
scan_barcode	Look up a product by UPC/EAN, flag its ingredients for a condition lens, and surface any active FDA recall
validate_claim	Fact-check a free-text health claim against Clarity's curated position — supports / contradicts / does-not-cover, with citation
check_interaction	Curated ingredient-to-ingredient interactions — type, severity, mechanism, clinical note, source (single or pair)
score_product	Category-specific product quality score by barcode (food / skincare / supplement), each dimension distinct, always with data-quality coverage
check_stack	Audit a supplement/ingredient stack in one call — per-item condition-lens verdicts (cited where evidence exists) plus curated within-stack interactions
find_alternatives	Find 2–3 safer same-category swaps for a flagged product, rated on Clarity's quality dimensions
check_recall	Check whether a consumer product or brand has an active FDA/consumer recall on file (food, supplements, cosmetics — not devices), with classification + source URL

Condition lenses: breastfeeding, lactation, pregnancy, histamine, mcas, rosacea, hs, allergy, all.

Anonymous use is rate-limited to 60 req/min per IP (Durable Object limiter); add an X-API-Key header for higher tiers. Descriptive and cited — not medical advice; absence of a flag is not proof of safety.
