Medical Terminologies MCP
io.github.SidneyBissoli/medical-terminologies-mcpUnified MCP server for six medical terminologies — ICD-11, LOINC, RxNorm, MeSH, ATC and the Brazilian CID-10 (Portuguese) — with authoritative WHO ICD-10→ICD-11 mapping, cross-terminology search and provenance (source, version, timestamp) on every response. Read-only retrieval, not clinical decision support. Remote (Streamable HTTP, no auth, no credentials) or local stdio.
