Paper Map → proof/citation evidence → scholarly reference resolver → Markdown reading reports and bounded cross-paper expansion. Explicit about extraction limits: empty evidence is reported as extraction failure, not invented math. uvx install from pinned GitHub tags; stdio MCP for research agents.","theCatch":"Vs generic RAG over PDFs: PaperGraph is theorem/evidence workflow for math papers, not a general document Q&A store. Does not verify proofs or equate similarly worded theorems; paywalled refs stay blocked unless you supply local PDFs.","verdict":"MIT evidence-first math-paper MCP. Use when agents must cite source spans instead of guessing dependencies.","addedAt":"2026-09-21","featured":false,"domain":"AI Agents","subSpecialty":"Agents","subcategory":"MCP","tags":["mcp","self-host","permissive","active","young-repo"],"capabilities":["mcp"],"surfaces":["MCP","Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"OSS/MIT","githubStars":285,"starsPerWeek":42,"access":"free","archived":false,"repo":{"createdAt":"2026-09-02","pushedAt":"2026-10-18","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/papergraph-mcp","html":"/gems/papergraph-mcp","markdown":"/gems/papergraph-mcp.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
