XHelio SPICE
Wire heliophysics or spacecraft ephemeris into an agent without hand-managing NASA SPICE kernel downloads and paths.
Overview
XHelio-SPICE is an MCP server for the Idea phase that auto-manages SPICE kernels so agents can answer heliophysics ephemeris questions without manual NAIF file handling.
What is this MCP server?
- Auto-managed SPICE kernel cache with optional XHELIO_SPICE_KERNEL_DIR override
- PyPI stdio MCP package (xhelio-spice) for local agent wiring
- Heliophysics-focused ephemeris without manual NAIF kernel bookkeeping
- stdio transport suitable for Claude Code and Cursor MCP configs
- Server version 0.5.1
- PyPI identifier xhelio-spice with stdio transport
- Optional env XHELIO_SPICE_KERNEL_DIR for cache override
What problem does it solve?
Managing SPICE kernel downloads and cache paths breaks agent-assisted research loops and wastes time before you know the science idea is worth building.
Who is it for?
Indie or solo builders prototyping heliophysics tools, mission analysis scripts, or agent demos that need real SPICE-backed positions.
Skip if: Teams who only need generic REST APIs, mobile app maps, or workflows with zero astronomy or spacecraft context.
What do I get? / Deliverables
After install, your agent can query managed ephemeris data through MCP while kernels stay in a predictable cache under your control.
- Locally cached SPICE kernels under default or custom directory
- Agent-callable ephemeris tooling over MCP stdio
- Repeatable research workflows without per-query manual kernel fetches
Recommended MCP Servers
Journey fit
Ephemeris and kernel research sits at the research phase before you commit sensors, simulations, or mission tooling to a full build. Research subphase covers downloading, caching, and validating planetary and spacecraft kernels—the first step in any SPICE-based analysis pipeline.
How it compares
Scientific ephemeris MCP integration, not a general calendar or geocoding API skill.
Common Questions / FAQ
Who is XHelio SPICE for?
It is for developers and researchers building heliophysics or spacecraft tooling who want agents to use SPICE kernels without manual kernel maintenance.
When should I use XHelio SPICE?
Use it during early research when ephemeris accuracy matters and you are still validating whether your pipeline or agent workflow is feasible.
How do I add XHelio SPICE to my agent?
Install the PyPI package xhelio-spice, optionally set XHELIO_SPICE_KERNEL_DIR, and register the stdio MCP server in Claude Code, Cursor, or another MCP-capable client.
