OpenArx is a Model Context Protocol (MCP) server: Open scientific and engineering knowledge for AI agents: search, evidence, document publishing. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://mcp.openarx.ai/researcher/mcp and you're connected, with nothing to install locally. The current release is v0.3.2, published under the Apache-2.0 license, with source at OpenArx-AI/openarx-core on GitHub.
You'll find OpenArx in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
