Injecting OA Status Directly into Code

Use the `get_article_oa_status` tool to find out if a DOI points to open access material. When running in Cursor's Agent mode, the AI calls this function and injects the real status data right where you’re writing code. This isn't mock data; it's live API context that lets you build logic based on actual paper availability.

Automating Full-Text Link Lookups

The tool pulls Open Access status and multiple full-text PDF links using a DOI. You can write code blocks that use this data structure, making your scripts much more reliable. Instead of writing placeholder URLs, the AI uses `get_article_oa_status` to populate variables with real, working download paths.

Writing Code with Knowledge Management via MCP Server

When you're mid-coding and need academic data, Cursor's Agent mode lets the MCP Server work for you. You just ask it to check a DOI, and it executes `get_article_oa_status`, giving you immediate results. This means your code generation process is informed by real-world scholarly context.
