mcp-horizons-nasa
by pipeworx-io
Provides tools for interacting with NASA's JPL Horizons system, enabling AI agents to resolve object names to SPK IDs and generate ephemeris data (observer and vector tables).
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-horizons-nasaget ephemeris for Mars on 2025-03-01"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"horizons-nasa": {
"url": "https://gateway.pipeworx.io/horizons-nasa/mcp"
}
}
}Or connect to the full Pipeworx gateway for access to all 673+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Horizons Nasa data" })The gateway picks the right tool and fills the arguments automatically.
