priorwork-mcp

MCP server for priorwork.fyi — semantic search over 114,000+ papers from major ML, NLP, and Computer Vision conferences (NeurIPS, CVPR, ICML, ICLR, ACL, EMNLP, ICCV, AISTATS, and more), directly from Claude Code, Cursor, or any MCP client.

Tools

Tool	Description
`search_papers`	Semantic search from a text query (a short descriptive sentence or two works slightly better than a few keywords) — returns ranked papers with authors, venue, year, similarity score, download URL, and full abstract. Pass `summarize=true` to add a structured per-paper LLM summary (problem, core insight, method, key results, positioning)
`search_by_pdf_url`	Give it a public PDF link (e.g. an arXiv PDF) and get semantically similar papers from the index
`list_indexes`	List the available paper indexes and their sizes

Setup

Claude Code

claude mcp add priorwork -- uvx priorwork-mcp

Cursor / other MCP clients
