Scholar MCP gives your AI agent a research library. It searches scholarly sources in parallel, with optional keys for additional indexes, follows citations and related work, reads the original paper down to its figures and tables, and keeps what matters in a local library with your notes. It works in Claude, Codex, Cursor, VS Code, Gemini CLI, OpenCode and any other MCP client, and from the command line or Python. Free for research and education, with commercial licenses for companies.

📰 News

• November 2026, 0.10.0. Searches no longer wait on a source whose connection hangs, OpenAlex's daily allowance lasts about four times as long, and Scholar is free for research and education under PolyForm Noncommercial, with commercial licenses for companies.
• November 2026, 0.9.0. scholar-mcp install sets Scholar up in 32 agents, one key file serves all of them, a slow source no longer holds up the others, and scholar-mcp doctor --network checks every link.
• October 2026, 0.8.5. Google Scholar sessions recover on their own, and arXiv falls back to its own search when its API is down.

🚀 Get started

1. Install uv if you do not have it, then install Scholar:

   bash

   uv tool install --python 3.12 --find-links https://github.com/Liyux3/scholar-mcp/releases/latest/download/wheel-index.html "scholar-mcp[rerank]"

2. Connect it to your agents. Scholar finds the clients on your machine and registers itself, with a backup of every file it touches:

   bash

   scholar-mcp install --all

   In a client the installer does not know, ask your agent to install Scholar by following llms-install.md. Name clients to choose (scholar-mcp install claude-code codex), add --dry-run to preview the change, or --profile research for the citation graph and paper library tools. scholar-mcp update upgrades the command every connected client runs, and uvx scholar-mcp@latest install CLIENT refreshes a client pinned to a uvx version.

3. Restart the client and ask a research question, for example find recent work on evaluating long-term memory in LLM agents, read the most cited one and compare its benchmarks.

{  "mcpServers": {    "scholar": {      "command": "uvx",      "args": [        "--python", "3.12",        "--find-links", "https://github.com/Liyux3/scholar-mcp/releases/latest/download/wheel-index.html",        "--from", "scholar-mcp[rerank]", "scholar-mcp"      ]    }  }}

🧰 What your agent can do

Every identifier Scholar returns, a paper URL, or an exact title can be passed back to any tool. Responses carry readable YAML for the model and structured data for the client; scholar://status reports the sources and reranker in use.

🧭 How it works

Your question goes to every source at once, in the form each one searches best, and no source holds up the others. Records from OpenAlex, Semantic Scholar, arXiv, Crossref, OpenReview, PubMed, Europe PMC, DBLP, zbMATH, CORE, OpenAIRE, Google Scholar and others merge on shared DOIs, arXiv ids and titles, so each paper appears once with complementary metadata. A ranking model, in the cloud or on your machine, orders the pool, the strongest papers bring in their citations and references, and everything is ranked together. The architecture page shows what each stage does for you and the backend film follows one question through it in two and a half minutes.

📊 Measured retrieval quality

[LitSearch quality comparison]

On the same 50 LitSearch queries, Scholar placed a correct paper in its top five for 62% of queries, against 52% for Exa research-paper search and 46% for BM25.

📚 Your paper library

[Real paper-library graph]

Saved papers, PDFs and notes live in one local SQLite library and stay searchable across sessions. Obsidian receives a live Markdown projection, Zotero a synchronized collection and Notion a reading list. Notes you edit in Obsidian or Notion flow back, so your agent builds on your changes.

scholar-mcp library export obsidian --collection memory --path ~/Vaultscholar-mcp library sync zotero --collection memory --apply

💻 Command line and Python

The tools work without an agent too. Output is YAML for reading or JSON with --json.

scholar-mcp search "long-term memory benchmarks for LLM agents" --year 2024-2026scholar-mcp read arXiv:2504.19413 --pages 1-4scholar-mcp read arXiv:2504.19413 --visual "Figure 1" --image figure1.pngscholar-mcp doctor --network

from scholar_mcp import api
hits = api.search("long-term memory benchmarks for LLM agents", year="2024-2026")paper = api.info(hits["results"][0]["id"], include="detail,citations")

🔑 Configuration

Scholar works without any keys. Optional keys add coverage and throughput. scholar-mcp keys set NAME saves one in ~/.scholar-mcp/keys.env, which every client reads; a client's env block or your shell also works and takes precedence.

export LIBRARY_PROXY_PREFIX="https://proxy.library.example.edu/login?url="export LIBRARY_PROXY_COOKIES="$HOME/private/library-cookies.txt"

🔧 Development

git clone https://github.com/Liyux3/scholar-mcp.gitcd scholar-mcpuv sync --extra devuv run pytest            # unit tests; live API tests run with -m integration

A new source is one module in scholar_mcp/sources/ plus one registry entry, and needs no new tool. scholar-mcp doctor --network probes every source, the ranking model and the PDF chain, and runs daily in CI. See CONTRIBUTING.md for changes, and report security issues through SECURITY.md.
