Overview
What is Scholar_mcp_server?
Scholar_mcp_server is a Go‑based MCP (Model Context Protocol) service that aggregates scholarly paper search results from multiple academic databases. It provides a unified interface with intelligent deduplication, merging, and sorting, designed for researchers who need to query several sources simultaneously.
How to use Scholar_mcp_server?
Clone the repository, run go mod tidy, then start the server with go run main.go logging.go. Optionally set environment variables SCOPUS_API_KEY and ADSABS_API_KEY to enable those sources. The server listens on http://127.0.0.1:8080/; configure an MCP client (e.g., Claude Desktop) to use the endpoint http://127.0.0.1:8080/mcp. Use the tools searchScholarPapers and getScholarPaper via JSON‑RPC calls.
