PaperGraph MCP is an evidence-first reading server for math papers, published from a personal repository under the MIT license and speaking MCP over stdio. Its core value is tying results, proofs, and citations to source spans that can be sliced back out of the original paper, while explicitly framing empty results as extraction limits rather than mathematical facts. It suits readers who insist on reviewing evidence, and does not suit those expecting proof verification, semantic equivalence judgments, or automatic crawling of the citation chain.
PaperGraph MCP is a local, evidence-first reading workflow server for AI agents working with math papers. It turns arXiv papers, local LaTeX projects, and born-digital PDFs into a theorem-centered local workspace so a researcher can inspect where every claim came from: extract results, trace proof evidence, plan reading order, review external dependencies, and keep reading state locally. It communicates over stdio, stores workspaces as ordinary local SQLite files, and adds a Scholarly Reference Resolver in v1.1.3 for metadata search of blocked references across Crossref, OpenAlex, and arXiv.
