HelioSPICE

HelioSPICE is an MCP (Model Context Protocol) server that provides programmatic access to spacecraft ephemeris data, making it easy to obtain positions, velocities, and perform coordinate transformations for various heliophysics missions. It wraps the SpiceyPy package, handling automatic SPICE kernel download, caching, and loading, and exposes several tools to AI assistants and MCP-compatible clients. It is ideal for researchers, engineers, and developers working with space mission data who need precise, automated access through LLMs, agents, or Python code.
