Common questions about Unpaywall (Open Access Papers) MCP in Cline

You add the MCP Server to Cline via its settings. Once connected, you treat it like any other API—you call `get_article_oa_status` directly within your code logic. It's treated as a standard data source.

Yep. Tell Cline to run the tool with specific DOIs, and it will retrieve the OA status and any associated PDF links. It's built for that kind of precise data retrieval.

The server returns structured, machine-readable JSON data detailing the status and location. This means your code can parse it instantly without any messy string manipulation.

Definitely. If your project needs to validate external scholarly sources, letting Cline handle the API calls keeps your core logic clean and focused on development.

It touches DOI identifiers and corresponding open access metadata. Your code uses this server to read that status information, but it doesn't modify any live records.
