Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Search and fetch research datasets across Zenodo, DataCite (Dryad/Figshare/Dataverse/OSF), NCBI omics (GEO/SRA/BioProject), and literature (PubMed/OpenAIRE) behind one normalized model — DOI deduplication, NCBI-Taxonomy synonym expansion, paper→data linking, and checksum-verified download. uvx data-aggregator-mcp.
MCP server for SPARKIT, a scientific research agent that searches the literature, reads papers, and returns cited Markdown reports. Submit a question via the research tool from Claude Desktop / Cursor / Claude Code; get back a 90-second cited report without leaving the chat. uv tool install sparkit-mcp or pip install sparkit-mcp.
