Cosmik MCP Server

Connect Cosmik to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Live space data for AI agents - rocket launches, ISS passes, launch news. Free, no auth. The cosmik mcp server is what makes that connection.

What the server does

Live space data for AI agents — the MCP server behind Cosmik, the free real-time 3D satellite tracker.

Cosmik tracks the ISS, Starlink and 20,000+ satellites in real-time 3D in any browser — free, no login. This server exposes the same live data (CelesTrak orbital elements, Launch Library 2) to AI agents. No API key, fair use; data refreshes continuously.

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• get_next_launches — Upcoming rocket launches worldwide — provider, pad, T-0, mission, webcast
• get_iss_passes — Next visible ISS passes for a city (550+ known) or any lat/lon — live SGP4 propagation
• get_launch_news — Latest launch news articles (7 languages)

Worth knowing first

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Cosmik's toolset — get_next_launches, get_iss_passes, get_launch_news — is a fair guide to whether it matches your workflow. It is maintained by com.gocosmik; worth a glance at recent repository activity before you build anything load-bearing on it.
