Roots by Benda — Cosmetic Regulatory Intelligence MCP Server

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.

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)

Data

100% source-traceability: every row has a src_local_path pointing at a specific primary-source file on disk and a src_verification_status in the verified set. No QSAR predictions, no unsourced aggregates.

Sources: SCCS opinions (EU Scientific Committee on Consumer Safety), CIR reports (Cosmetic Ingredient Review), EFSA evaluations, ECHA REACH dossiers, EPA ToxValDB, FDA databases, Korea MFDS, Japan MHLW, ASEAN Cosmetic Directive Annex II, Saudi SFDA, Health Canada Hotlist, Australia SUSMP/TGA, California Office of Environmental Health Hazard Assessment (Prop 65), California AB-2762 / AB-496, Washington SB 5369.
