Knowledge graph

The search backend also maintains a biomedical knowledge graph (1.3M+ entities, 109M+ paper links) with genes, diseases, drugs, proteins, institutions, researchers, topics, genetic variants, and drug-target-disease relationships sourced from PubTator Central, DisGeNET, ChEMBL, UniProt, ROR, ORCID, Open Targets, and others.

Tools

Tool	What it does
`search_papers`	Full-text + semantic hybrid search with year/citation/source filters
`get_paper`	Fetch metadata by DOI, PMID, arXiv ID, or OpenAlex ID
`find_similar`	Find papers related by meaning, not just keyword matching
`get_citation_graph`	Citation network — references and citing papers
`search_by_entity`	Find papers linked to a gene, drug, disease, or institution via the KG
`create_literature_review`	AI-generated structured lit review with citations (Pro)

Get an API key

All usage requires a free NobleBlocks account. Sign up takes 30 seconds:

Go to nobleblocks.com/signup
Create an account (email or Google)
Navigate to Settings > API Keys and generate a key

Free plan: 100 searches/day, 5 similar/day, citation graph access. Pro plan: 5,000 searches/day, literature review generation, priority support.

Quick start (Remote — no install needed)

The easiest way to get started is the remote connector — no API keys, no Python install:

Open claude.ai → Settings → Connectors (or Integrations)
Click "Add" and paste: https://mcp.nobleblocks.com/mcp
Sign in with your NobleBlocks account
