MCPOrbital: an open source MCP server for space data

Language models tend to make up numbers about space. MCPOrbital is my own MCP server that connects Claude, Cursor and other AI assistants to real data from NASA JPL, NOAA, CelesTrak, the NASA Exoplanet Archive and arXiv, with a source on every answer.

In short

MCPOrbital is an open source MCP server with 11 tools: asteroids and close approaches, impact risk, space weather, satellite orbits, ephemerides and exoplanets. Ask an AI assistant when Apophis comes closest to Earth, and it fetches the answer from NASA JPL: 13 April 2029 at 21:46 UTC, about 38,011 km from Earth, with the source next to it.

Why

An AI assistant that answers from memory can get dates, distances and risks wrong. An MCP server gives it tools to fetch fresh numbers from the source instead of guessing, and to show where the numbers come from.

What I built

  1. Research first. 12 documents on APIs, market, the MCP spec, architecture and roadmap, and 42 APIs researched.
  2. An MCP server in TypeScript. 11 tools with input validation, and source, license and timestamp on every answer.
  3. Safety. The server refuses requests to command satellites.
  4. A website. Next.js with 12 pages and 13 API routes, where research briefs export as .md or .bib.
  5. Agent skills. A skill for Claude and one for OpenClaw with four agents.
  6. Hosting. On my own server with systemd, nginx and Let's Encrypt, with a public health check.

The result

The server is live with 11 tools, and the code is open on GitHub under the Apache 2.0 license. The answers in the illustration above are real answers from the server on 31 October 2026.

The same technique can connect an AI assistant to your CRM, your bookings or your prices, so it answers with your numbers instead of guessing.

Questions and answers

What is an MCP server?

MCP (Model Context Protocol) is an open standard that lets AI assistants like Claude use tools and data outside the model. An MCP server offers such tools, for example fetching data from an API.

Why cite a source on every answer?

So you can check the number yourself, and the AI assistant can show where the answer comes from. That makes the answers safer to use in research and work.

Can an MCP server connect AI to my business data?

Yes. The same approach can give an AI assistant access to your inventory, prices, open time slots or CRM customers, so it answers staff and customers with correct numbers.

Can I use MCPOrbital?

Yes, the code is open on GitHub under the Apache 2.0 license.
