🧬 BioBTree v2

A unified biomedical graph database that integrates 50+ primary data sources — genes, proteins, compounds, diseases, pathways, and clinical data — into a single queryable graph with billions of cross-reference edges. Its native MCP server gives LLMs direct access to structured, authoritative biomedical data, complementing their reasoning with reliable identifiers and up-to-date database content.

BRCA1 >> ensembl >> uniprot >> pdb[resolution<2.0]

This finds BRCA1 in Ensembl, maps to UniProt proteins, and returns high-resolution PDB structures — crossing three databases in a single line.

🔗 Try It

The fastest way to experience BioBTree v2 is through MCP. We recommend Claude CLI (tested extensively), though Codex CLI and Gemini CLI also work:

{
  "mcpServers": {
    "biobtree": {
      "type": "http",
      "url": "https://sugi.bio/biobtree/mcp"
    }
  }
}

Once connected, just ask questions in natural language — the AI will query BioBTree automatically:

💊 "What tissues express SCN9A most highly? Are there safety concerns for a Nav1.7 inhibitor?"

🧪 "How many ClinVar variants does BRCA1 have? How many are pathogenic?"

🎯 "What are all the protein targets of Alectinib with IC50 values?"

A REST API is also available for direct programmatic access:
