A side-by-side look at the Arxivsub MCP and Find Research Papers MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Arxivsub MCP for research work as a local process; choose Find Research Papers for research as a local process. You can also run both side by side in one mcpServers block.
ARXIVSUB_SKILL_KEY.search_papers, find_similar_papers, research_insight.search_papers, get_paper, get_research_method.Rows where the two servers differ are marked.
