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

| Tool | What it does | |------|-------------| | lookup_icd10 | Search ICD-10-CM codes by diagnosis name or code | | lookup_meddra | MedDRA PT lookup with SOC, hierarchy, and synonyms | | lookup_rxnorm | RxNorm drug concept, RxCUI, ATC class, brand/generic mapping | | crossmap_icd_meddra | Cross-map between ICD-10 and MedDRA with regulatory context | | search_medical_concept | Broad concept search across ICD-10, MedDRA, RxNorm | | lookup_ctcae | CTCAE v5.0 grading criteria for oncology adverse events |

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

Data Sources

All free, public APIs — no API key required:

• ICD-10-CM: NIH NLM Clinical Tables API
• RxNorm: NIH NLM RxNav API
• MedDRA SOC/hierarchy: MedDRA v26.0 public documentation
• CTCAE v5.0: NCI Cancer Therapy Evaluation Program

⚠️ MedDRA full term browser requires subscription at meddra.org. This server provides hierarchy navigation and curated PT reference data based on public documentation.
