Description
NobleBlocks operates a research search engine indexing more than 300 million scholarly works across sources such as OpenAlex, PubMed, arXiv, bioRxiv, and CrossRef, refreshed daily. On top of this corpus it layers AI-driven features including natural-language search, systematic and agentic 'Deep Review' literature reviews, PDF chat with cited answers, citation-graph exploration, and open-access-first paper surfacing. The platform is distributed as a web application and as a Model Context Protocol (MCP) server offering 8 research tools and 15 pre-built prompts (e.g., literature review, systematic review protocol, research gaps, clinical evidence) that integrate with Claude Desktop, Claude Web, Cursor, VS Code Copilot, Windsurf, and Cline. Its typical clients are scientists, clinicians, and graduate students conducting literature reviews, systematic reviews, and evidence synthesis; accounts are required for MCP access, with a free tier offering 100 queries/day. The site also references a NOBL token contract address in its footer.
