Paper Search MCP is a Python-based MCP server that enables searching and downloading academic papers from multiple sources through a free-first strategy prioritizing open access and public data. It provides tools for paper search across multiple platforms with deduplication, PDF downloading with fallback mechanisms, and text extraction, designed to support both MCP clients like Claude Desktop and Claude Code workflows. The server solves the problem of fragmented academic paper access by offering a unified interface to various sources while keeping advanced source-specific connectors extensible for users.
