Xraylib Mcp Server

Gives Claude direct access to xraylib's X-ray interaction database through 104 specialized tools. You get fluorescence line energies, absorption edge data, mass and atomic cross-sections for photoelectric, Rayleigh, and Compton interactions, plus scattering factors, refractive indices, and Auger transition rates. Parse chemical formulas, query the built-in NIST compound database, or pull radionuclide decay data. Runs via stdio for Claude Desktop, supports HTTP and SSE transports, and ships as a Docker image. Useful when you're doing X-ray fluorescence analysis, modeling photon transport, or need atomic physics constants without leaving your AI workflow.
