The XTB MCP Server is a Model Context Protocol (MCP) server that provides comprehensive tools for generating Extended Tight-Binding (XTB) quantum chemistry calculation input files. This server integrates seamlessly with AI assistants like Claude, Cursor, and Windsurf to enable intelligent quantum chemistry workflow automation.
ABACUS, an open-source DFT-based simulation platform, is supported by an MCP server that provides a structured communication interface for submitting, managing, and executing tasks.
