About Semantic Scholar MCP Server

Semantic Scholar MCP Server is an MCP server published by the GitHub account smaniches. MCP server for the Semantic Scholar API: search 200M+ papers, citations, authors, recommendations.

It runs on your own machine: your AI client starts it from the PyPI package s2-mcp-server at version 1.7.12.

It asks for one secret: SEMANTIC_SCHOLAR_API_KEY. Give it a key with the least access that still works.

Version 1.7.12 was published on 27 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
