Cosmetic Regulatory

rootsbymenda/roots-mcp-server
HTTP, SSEregistry active
Summary

Gives Claude direct access to cosmetic ingredient safety data across 12 regulatory jurisdictions including EU Regulation 1223/2009, US FDA, Korea MFDS, and California Prop 65. You get four tools: check_ingredient for full regulatory profiles with SCCS opinions and pre-calculated Margin of Safety values, check_formula for batch compliance scans of up to 50 ingredients, search_ingredients for discovery when you don't know the exact INCI name, and calculate_mos for safety assessments using SCCS methodology. The database contains 884,345 rows of NOAEL studies, dermal absorption data, and regulatory opinions with full source traceability. Built by a cosmetic formulator, this replaces €16,000/year commercial databases with a free Cloudflare Workers endpoint backed by D1 SQLite.

Roots by Benda — Cosmetic Regulatory Intelligence MCP Server

smithery badge

The world's first cosmetic-regulatory MCP. Check cosmetic ingredient safety and multi-jurisdiction compliance — EU Regulation 1223/2009, US FDA, Korea MFDS, Japan MHLW, ASEAN, Saudi SFDA, Canada Hotlist, Australia SUSMP, ECHA SVHC, California Prop 65, California TFCA, Washington TFCA — backed by 884,345 rows of SCCS opinions, NOAEL studies, CIR conclusions, and pre-calculated Margin of Safety values.

Equivalent data licensed from commercial providers (Coptis, CosmEthics) runs €16,000/year. This MCP is free.

Live endpoint: https://roots-mcp-server.rootsbybenda.workers.dev/mcp SSE fallback: https://roots-mcp-server.rootsbybenda.workers.dev/sse

Tools

check_ingredient

Full regulatory profile for a single cosmetic ingredient by name, INCI name, or CAS.

Returns: SCCS safety opinion, EU Annex II/III/V/VI classification, pre-calculated Margin of Safety, NOAEL reference, dermal absorption, sensitization profile, CIR conclusion, endocrine-disruptor status, ECHA SVHC listing, China IECIC status, plus jurisdictional_profile — the regulatory status across all 12 supported jurisdictions in one response.

query: "retinol"
→ EU: restricted (0.05% body, 0.3% face); Korea_MFDS: restricted; California_Prop65: (not listed);
  SCCS/1639/21 — MoS 167 @ 0.3% face cream (pass); NOAEL 0.43 mg/kg bw/day

check_formula

Batch compliance scan for an INCI deck (up to 50 ingredients). Returns per-ingredient regulatory status, flagged restricted/banned substances, and overall formula risk level.

ingredients: "Aqua, Retinol, Cetearyl Alcohol, Titanium Dioxide, Phenoxyethanol"
jurisdiction: "EU"
→ Risk: MODERATE — 1 flagged (Retinol — restricted max 0.05% body leave-on under Annex III/321)

search_ingredients

Discovery search when you don't know the exact INCI. Filter by partial name, function, or category.

query: "sunscreen" → 10 matches (UV filters with safety ratings and EU status)
query: "preservative" → parabens, phenoxyethanol, benzyl alcohol, etc.

calculate_mos

Margin of Safety calculator per SCCS Notes of Guidance (SCCS/1647/22) methodology. Returns SED, MoS value, and pass/fail against the SCCS-100 threshold used in CPSR safety assessments.

ingredient: "retinol", concentration: 0.3, product_type: "face cream"
→ SED 0.129 mg/kg bw/day; MoS 333 (pass, >100 threshold); dermal absorption 40% (SCCS/1639/21)
