XHelio-SPICE

XHelio-SPICE is a Python library and MCP server for heliophysics research that automates the management, downloading, caching, and loading of NAIF SPICE kernels for a variety of spacecraft and solar system bodies. It provides straightforward APIs and an MCP interface for querying spacecraft positions, trajectories, velocity vectors, coordinate transformations, and more, returning results as Python dicts or pandas DataFrames. It's designed for scientists, developers, and researchers working on solar system missions and heliophysics data analysis, with special support for integration into LLM toolchains and platforms like Claude Desktop.
