nobleblocks-mcp — Claude Code MCP server: paper search
Search academic papers by meaning and citation links, retrieve records, compare related work, and build cited literature reviews.
claude mcp add --transport http nobleblocks-mcp https://mcp.nobleblocks.com/mcpWhat nobleblocks-mcp does
nobleblocks-mcp connects Claude Code and other MCP clients to an index containing 340M+ academic records. Its tools support hybrid paper search, metadata lookup by DOI, PMID, arXiv ID, or OpenAlex ID, semantic similarity, and citation-network queries.
A biomedical knowledge graph links papers with genes, drugs, diseases, institutions, and other entities. create_literature_review produces a structured cited review on the Pro plan. Local use requires a NobleBlocks account and NOBLEBLOCKS_API_KEY; without that key, the local server cannot call the API. A remote setup uses https://mcp.nobleblocks.com/mcp.
What it helps with
- search papers with year and source filters
- retrieve a record from its DOI or PMID
- find research related by meaning
- trace references and citing papers
- connect a gene or drug to related studies
Example prompts for the agent
- Find the most-cited papers about CRISPR base editing from 2022-2024.
- Show papers semantically related to “Attention Is All You Need”.
- Build a citation graph for DOI
