A Model Context Protocol (MCP) server that enables LLMs to search, download, and read arXiv papers. Gives AI assistants direct access to scientific literature.

## Features

- **Search papers** - Search by title, keywords, author, or arXiv ID
- **Read full text** - Download PDFs and extract text automatically
- **Section extraction** - Get specific sections (abstract, introduction, methods, conclusion)
- **Local caching** - Downloaded papers are cached locally for fast re-access
- **Zero configuration** - Works out of the box with sensible defaults

## Getting Started

### Prerequisites

This MCP server uses `uvx` to run. First, install `uv`:

```bash
# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Or using Homebrew
brew install uv
```

After installation, restart your terminal.

### Installation

Install the arXiv MCP server with your client.

Standard config works in most tools:

```json
{
  "mcpServers": {
    "arxiv": {
      "command": "uvx",
      "args": ["arxiv-paper-mcp-server"]
    }
  }
}
```

| `ARXIV_STORAGE_DIR` | Directory for downloaded papers | `~/.arxiv-mcp/papers` |

## Usage Examples

**Search for papers:**
```
User: Find recent papers about prompt compression

Claude: [Uses search("prompt compression", max_results=5)]
Found 5 papers:
- 2504.16574: PIS: Linking Importance Sampling...
- ...
```

**Read a specific paper:**
```
User: Read the introduction of paper 2401.12345

Claude: [Uses get_paper("2401.12345", section="introduction")]
[Returns the introduction section]
```

**Review cached papers:**
