    }
  }
}

ArXiv MCP Server tools

Search for papers on arXiv with advanced filtering and query optimization. QUERY CONSTRUCTION GUIDELINES: - Use QUOTED PHRASES for exact matches: "multi-agent systems", "neural networks", "machine learning" - Combine related concepts with OR: "AI agents" OR "software agents" OR "intelligent agents" - Use field-specific searches for precision: - ti:"exact title phrase" - search in titles only - au:"author name" - search by author - abs:"keyword" - search in abstracts only - Use ANDNOT to exclude unwanted results: "machine learning" ANDNOT "survey" - For best results, use 2-4 core concepts rather than long keyword lists ADVANCED SEARCH PATTERNS: - Field + phrase: ti:"transformer architecture" for papers with exact title phrase - Multiple fields: au:"Smith" AND ti:"quantum" for author Smith's quantum papers - Exclusions: "deep learning" ANDNOT ("survey" OR "review") to exclude survey papers - Broad + narrow: "artificial intelligence" AND (robotics OR "computer vision") CATEGORY FILTERING (highly recommended for relevance): - cs.AI: Artificial Intelligence - cs.MA: Multi-Agent Systems - cs.LG: Machine Learning - cs.CL: Computation and Language (NLP) - cs.CV: Computer Vision - cs.RO: Robotics - cs.HC: Human-Computer Interaction - cs.CR: Cryptography and Security - cs.DB: Databases EXAMPLES OF EFFECTIVE QUERIES: - ti:"reinforcement learning" with categories: ["cs.LG", "cs.AI"] - for RL papers by title - au:"Hinton" AND "deep learning" with categories: ["cs.LG"] - for Hinton's deep learning work - "multi-agent" ANDNOT "survey" with categories: ["cs.MA"] - exclude survey papers - abs:"transformer" AND ti:"attention" with categories: ["cs.CL"] - attention papers with transformer abstracts DATE FILTERING: Use YYYY-MM-DD format for historical research: - date_to: "2015-12-31" - for foundational/classic work (pre-2016) - date_from: "2020-01-01" - for recent developments (post-2020) - Both together for specific time periods RESULT QUALITY: Results sorted by RELEVANCE (most relevant papers first), not just newest papers. This ensures you get the most pertinent results regardless of publication date. TIPS FOR FOUNDATIONAL RESEARCH: - Use date_to: "2010-12-31" to find classic papers on BDI, SOAR, ACT-R - Combine with field searches: ti:"BDI" AND abs:"belief desire intention" - Try author searches: au:"Rao" AND "BDI" for Anand Rao's foundational BDI work

Overview

What is ArXiv MCP Server?

The ArXiv MCP Server provides a bridge between AI assistants and arXiv’s research repository through the Model Context Protocol (MCP). It allows AI models to search for papers and access their content in a programmatic way. The server is for anyone who wants to integrate arXiv paper discovery and retrieval into AI‑powered workflows.

How to use ArXiv MCP Server?

Install the server via Smithery (npx -y @smithery/cli install arxiv-mcp-server --client claude), using the one‑click .mcpb bundle for Claude Desktop on macOS, or manually with uv tool install arxiv-mcp-server. Then add the appropriate MCP configuration (stdio or HTTP) to your client’s config file. The server exposes tools such as search_papers, download_paper, read_paper, list_papers, and semantic_search.

Key features of ArXiv MCP Server

  • Search arXiv with filters for categories, date ranges, and boolean operators.
  • Download paper content (HTML first, with PDF fallback).
  • Read paper content with paging support for large documents.
  • List all locally downloaded papers.
  • Local storage for faster repeated access.
  • Pre‑built research prompts for paper analysis.

Use cases of ArXiv MCP Server

  • Automate literature searches across arXiv categories and date ranges.
  • Download and analyze research papers within an AI assistant workflow.
  • Build a local library of papers for offline reading and semantic search.

Frequently asked questions

1

How do I install ArXiv MCP Server?

Install via Smithery, Claude Desktop .mcpb bundle, or manually with `uv tool install arxiv-mcp-server`. Python 3.11+ must be available.

2

What are the Python requirements?

The server requires Python 3.11 or newer. For PDF‑only older papers, install the extra with `uv tool install 'arxiv-mcp-server[pdf]'`.

3

Is paper content safe to feed into AI assistants?

No. arXiv papers are untrusted user‑generated content and may contain prompt injection attacks. Treat all paper text as potentially adversarial, especially in agentic pipelines.

4

How does the server handle rate limits?

The server enforces arXiv’s 3‑second rate limit automatically. If rate‑limited, wait 60 seconds before retrying.

5

Can I run the server over HTTP instead of stdio?

Yes. Set the environment variables `TRANSPORT=http`, `HOST`, and `PORT` (e.g., `TRANSPORT=http HOST=127.0.0.1 PORT=8080 arxiv-mcp-server --storage-path /path/to/papers`) and use a Streamable‑HTTP–capable MCP client configured with the server’s URL.
