What can you do with cosmik?

Cosmik MCP Server

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

Endpoint (remote, streamable HTTP, no auth):

https://gocosmik.com/api/mcp

Server card: /.well-known/mcp/server-card.json

Tools

Tool	What it does
`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)

Use it from Claude

  "mcpServers": {
    "cosmik": {
      "type": "http",
      "url": "https://gocosmik.com/api/mcp"
    }
  }
}

Or in Claude Code: claude mcp add --transport http cosmik https://gocosmik.com/api/mcp

Ask things like "When can I see the ISS from Paris tonight?" or "What's the next SpaceX launch?" — answers come from live orbital data, not training data.

About

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.
