Overview
What is Semantic Scholar MCP Server?
A FastMCP server implementation for the Semantic Scholar API, providing comprehensive access to academic paper data, author information, and citation networks. It is designed for researchers, developers, and anyone needing programmatic access to scholarly content and citation analysis.
How to use Semantic Scholar MCP Server?
Install the server using FastMCP with the command fastmcp install semantic-scholar-server.py --name "Semantic Scholar" -e SEMANTIC_SCHOLAR_API_KEY=your-api-key. The API key is optional; without it the server uses unauthenticated access with lower rate limits. After installation, tools are available via any MCP client.
