Search, download, and read academic papers via the paper-search CLI.
All commands run via:
bashpaper-search <command> [args]
If paper-search is not available, install it with uv tool install paper-search-mcp. Optional API keys can be configured in ~/.config/paper-search-mcp/.env.
bashpaper-search search "<query>" -n <max_per_source> -s <sources> -y <year>
-n: results per source (default: 5)-s: comma-separated sources or "all" (default: all)-y: year filter for Semantic Scholar (e.g. "2020", "2018-2022")For speed, prefer targeted sources (-s arxiv,semantic,crossref) over "all" unless broad coverage is needed.
bashpaper-search download <source> <paper_id> [-o ./downloads]
bashpaper-search read <source> <paper_id> [-o ./downloads]
bashpaper-search sources
search and download return JSON. read returns plain text. Config warnings go to stderr and can be ignored.
