MedTerms MCP Server
Medical terminology intelligence for AI agents.
Built on free public NIH APIs. Covers ICD-10-CM, MedDRA, RxNorm, CTCAE v5.0, and cross-terminology mapping — the coding systems used in every regulatory submission, clinical trial, and pharmacovigilance report.
Tools

Who uses this
- Medical information agents — classify AEs against MedDRA for FAERS submissions
- Clinical trial agents — grade adverse events per CTCAE
- Drug safety agents — map diagnoses between ICD-10 and MedDRA
- Medical writing agents — look up correct PT for adverse reactions section
- Regulatory submission agents — validate terminology before ICH E2B submission
- EHR/EMR integration agents — translate between coding systems
