Runs on your machine under the source's own terms

The crw MCP on your computer calls bioRxiv directly. Calls cost no credits and the data does not pass through fastCRW. Install it once for Claude Code, Cursor, Codex, Windsurf, Gemini CLI or OpenCode, with your fastCRW API key in place of the placeholder:

Ask with this source

A prompt for your agent that names this source and how to call it through the crw MCP.

  • Preprints posted in a date range

    Use bioRxiv (biorxiv) from fastCRW Pergamon, capability "Preprints posted in a date range" (content-by-date). You want to sweep everything a preprint server posted over a specific period, optionally narrowed to one subject area. Example options: server=biorxiv, start=2025-03-21, end=2025-03-28. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "biorxiv" and capability "content-by-date". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Posting volume over time

    Use bioRxiv (biorxiv) from fastCRW Pergamon, capability "Posting volume over time" (content-stats). You want to chart or quote how bioRxiv's output has grown rather than look at individual papers. Example options: interval=m. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "biorxiv" and capability "content-stats". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Preprint detail

    Use bioRxiv (biorxiv) from fastCRW Pergamon, capability "Preprint detail" (details). You hold a bioRxiv or medRxiv DOI and want that preprint's metadata, abstract and version history. Example options: server=biorxiv, prefix=10.1101, suffix=2020.03.22.002386. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "biorxiv" and capability "details". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Preprints by research funder

    Use bioRxiv (biorxiv) from fastCRW Pergamon, capability "Preprints by research funder" (funder). You want everything a specific funding body - identified by its ROR ID - paid for on a preprint server. Example options: server=biorxiv, start=2025-04-10, end=2025-07-10. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "biorxiv" and capability "funder". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
