# How to Find Open Access Papers with Claude

Claude helps you navigate the open access landscape through iterative searching. Find papers on your topic, identify which are freely available, and explore alternative access routes for paywalled papers such as preprints on arXiv or author manuscripts. The conversation adapts to help you access the research you need.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Find open access papers on deep reinforcement learning using academic-research"
3. Claude returns papers with open access availability noted
4. Ask: "Which of these are freely available?"
5. Access the open versions directly

## Example Prompt

```
Find freely available papers on graph neural networks. I do not have journal access so I need open access versions only.
```

## Tips

- Many paywalled papers have free preprint versions on arXiv
- Ask Claude to check for open access versions of specific papers
- Author manuscripts on university repositories are usually legal open versions
