概要
What is XTB MCP Server?
The XTB MCP Server is a Model Context Protocol (MCP) server that provides tools for generating Extended Tight-Binding (XTB) quantum chemistry calculation input files. It integrates with AI assistants like Claude, Cursor, and Windsurf to automate quantum chemistry workflows.
How to use XTB MCP Server?
Clone the repository, install dependencies with pip install -r requirements.txt, and run tests with python run_tests.py. Configure the server in your MCP client (e.g., Claude Desktop, Cursor, or Windsurf) by adding a JSON entry pointing to the main.py script. Then invoke any of the ten available tools through your AI assistant.

- Analyze molecular dynamics trajectories with built‑in tools
FAQ from XTB MCP Server
What runtime dependencies does XTB MCP Server require?
Python and the packages listed in requirements.txt. No external XTB installation is needed because the server only generates input files, not runs them.
How do I configure the server with my MCP client?
Add a JSON entry to your client’s MCP settings (e.g., claude_desktop_config.json) with "command": "python" and the path to main.py as an argument.
What file formats are supported for structure conversion?
XYZ, COORD, and Gaussian input formats are supported for conversion.
Does the server run XTB calculations directly?
No. It only generates the input files and control scripts; the user must run the actual XTB calculation separately.
Is there any authentication or transport mechanism?
No authentication or special transport is mentioned; the server communicates via the standard MCP protocol using stdio.
