# How to Find Open Access Papers with ChatGPT

ChatGPT explains the open access ecosystem alongside search results. It describes the difference between gold and green open access, suggests the best preprint servers for your field, and helps you understand which papers are likely to have free versions available even when the primary source is paywalled.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Find open access papers on computational biology"
3. ChatGPT returns papers noting which are freely available
4. Request: "Show me only the ones I can read for free"
5. Access the open versions

## Example Prompt

```
Search for open access papers about drug resistance in cancer treatment. I need papers I can read without a subscription.
```

## Tips

- ChatGPT can explain the different types of open access
- Ask about preprint servers for your specific field
- Many funders now mandate open access -- recent papers are more likely to be free
