Cannabis MCP Server

Roots by Benda — Cannabis Regulatory Intelligence MCP Server

Cannabis testing requirements, controlled substance scheduling, and compliance data in one MCP. Check US state-level testing limits (pesticides, heavy metals, microbials, solvents, potency), UN/EU controlled substance schedules, Health Canada cannabis rules, and novel psychoactive substance monitoring — all source-linked and free.

No equivalent consolidated cross-jurisdiction cannabis compliance MCP exists. This is the first.

Tools

check_cannabis_testing

Look up cannabis testing limits by US state, test category, product type, or analyte. Returns pesticide, heavy metal, microbial, solvent, mycotoxin, potency, moisture, action-level, unit, and regulation-reference data.

state: "California", test_category: "heavy_metal"
→ Arsenic: 0.2 µg/g (inhalable), 1.5 µg/g (non-inhalable) — CA DCC 4 CCR §15723
  Cadmium: 0.2 µg/g (inhalable), 0.5 µg/g (non-inhalable)
  Lead: 0.5 µg/g (both categories)
  Mercury: 0.1 µg/g (inhalable), 3.0 µg/g (non-inhalable)
  8 limits found, all regulation-referenced

check_controlled_substance

Check whether a substance is controlled or scheduled under UN INCB narcotic schedules, EU drug-precursor controls, or EMCDDA/EUDA novel psychoactive-substance monitoring. Returns schedules, categories, synonyms, CAS numbers, and regulatory notes.

query: "psilocybin"
→ UN Schedule I (1971 Convention); CAS 520-52-5; Category: indole alkaloid;
  Status: no accepted medical use (UN), breakthrough therapy (FDA, 2018)

check_cannabis_compliance

Check cannabis product compliance requirements for a US state or Health Canada product class. Returns jurisdiction-specific testing categories, analyte limits, product classes, units, and regulation sections.

jurisdiction: "Colorado", product_class: "concentrate"
→ Testing required: potency, residual solvents, heavy metals, microbials, mycotoxins
  Per-analyte limits with regulation references (1 CCR 212-3)

search_cannabis_regulations

Search cannabis and controlled-substance regulatory data by keyword. Use for broad discovery across state testing limits, Health Canada cannabis rules, UN scheduling, EU precursors, and novel psychoactive substances.

query: "heavy metal"
→ matches across CA, CO, OR, WA state testing limits for Lead, Cadmium, Arsenic, Mercury
  with action levels, units, and product-type distinctions per jurisdiction
