Unofficial Open Targets MCP Server 🧬
Unofficial Model Context Protocol server for accessing Open Targets platform data for gene-drug-disease associations research.
Developed by Augmented Nature
✅ Verified Features
All 6 tools working with live Open Targets API data:
🎯 Target Search - Gene symbols, names, descriptions (BRCA1, TP53, etc.)
🦠 Disease Search - Names, synonyms, descriptions (cancer, diabetes, etc.)
🔗 Target-Disease Associations - Evidence scores from 20+ databases
📊 Disease Target Summaries - Prioritized therapeutic targets
🧬 Target Details - Comprehensive gene/protein information
🎭 Disease Details - Complete disease profiles with ontologies
🚀 Quick Start
# Install and build
npm install
npm run build
# Run the server
