Raras Disease Twin — MCP Server

Brazilian rare-disease knowledge graph (10,468 diseases) exposed via the Model Context Protocol (MCP). Each disease is an addressable Disease Twin (disease://{orphaCode}): genes, HPO phenotypes, SUS coverage, clinical trials, literature-mined treatments, repurposing hypotheses, and grounded multi-hop reasoning — PT-BR first, source-grounded, never diagnoses.
