Roots by Benda — Pharmaceutical & Bioequivalence Intelligence MCP Server

Drug safety, interactions, adverse events, and regulatory data in one MCP. Check any drug or active ingredient against DrugBank, WHO Essential Medicines, FDA FAERS adverse events, drug-drug interactions, Australian TGA ARTG, FDA NDI notifications, and ChEMBL bioactivity — all source-linked and free.

Equivalent data through commercial platforms (Lexicomp, Micromedex, DrugBank Pro) costs $20,000+/year. This MCP is free.

Code

query: "ibuprofen"
→ DrugBank: Ibuprofen (DB01050), CAS 15687-27-1, approved/investigational
  Targets: Prostaglandin G/H synthase 1 & 2, PPAR-gamma, CFTR
  Drug-Drug Interactions: 100
  WHO Essential: Yes — ATC M01AE01, analgesic/anti-inflammatory
  Formulations: IV 5 mg/mL; Oral 200/400/600 mg tablet; Liquid 100-200 mg/5 mL
  Dosage: 200-400 mg q6-8h; max 1200-2400 mg/day
  Contraindications: Active GI bleeding; severe renal impairment; third trimester pregnancy
  TGA ARTG: 10 registered products (BRUFEN 400mg, CALDOLOR IV, NUROFEN PLUS, etc.)

`check_drug_interactions`

Check drug-drug interactions for one drug or a specific pair. Returns interaction severity, mechanism, clinical effect, evidence level, and management recommendations for medication safety review.

Code

query: "warfarin aspirin"
→ Severity: MAJOR; Mechanism: additive anticoagulant + antiplatelet effect;
  Clinical: increased bleeding risk; Management: avoid combination or monitor INR closely

`check_adverse_events`

Check FDA FAERS adverse-event records for a drug or active ingredient. Returns total reports, serious outcomes, death reports, top adverse reactions, and common patient age groups.

Code

query: "isotretinoin"
→ Total reports: 12,847; Serious: 8,231; Deaths: 89; Top reactions: depression,
  inflammatory bowel disease, suicide attempt; Peak age: 15-25

`search_pharma`

Search across pharmaceutical regulatory and safety databases by keyword. Use for broad discovery across DrugBank, WHO Essential Medicines, TGA ARTG, FAERS, FDA NDI, drug interactions, and ChEMBL bioactivity.

Code

query: "SSRI pregnancy" → matches across FAERS (birth defects), interactions, DrugBank warnings
