mcp-horizons-nasa

NASA JPL Horizons — solar-system body ephemerides

Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.

Tools

Tool	Description
`lookup`	Resolve an object name → SPK id.
`ephemeris`	Generate an ephemeris (default observer table).
`observers`	Convenience: ephemeris with table_type=OBSERVER.
`vectors`	Convenience: ephemeris with table_type=VECTORS.

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 250+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

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.
