search-citation-mcp 1.1.1

Academic paper search and IEEE citation engine — MCP server with 9 tools

Search & Citation MCP

MCP server for academic paper search and IEEE citation generation. Searches across 3 sources in parallel (OpenAlex + Crossref + Semantic Scholar), generates biblatex-ieee BibTeX, validates entries, downloads PDFs, and maintains your bibliography — all through 9 LLM-accessible tools.

Install

pip install search-citation-mcp

No config required. Creates ./bibliografia.bib on first citation.
