Use Orbitwren MCP with Claude Code

Orbital data center & space AI compute tracker MCP: projects, launches, orbits, alerts. 100 free/day

Remote MCP server (Streamable HTTP), nothing to install. Free: 100 free/day · Paid: Alerts $5/mo; keys $9/mo; x402 $0.003/call

Set it up

Run the command in your terminal (add --scope user to use it in every project, or --scope project to write .mcp.json).
Start Claude Code and type /mcp to see the server and its tools.
Ask a question the tools can answer; Claude Code asks permission before each tool call unless you allow it.

Run:

claude mcp add --transport http orbitwren 'https://orbitwren.cybermaxtools.com/mcp?via=use-with-claude-code'

Or share it with your team in .mcp.json (project scope)::

{
  "mcpServers": {
    "orbitwren": {
      "type": "http",
      "url": "https://orbitwren.cybermaxtools.com/mcp?via=use-with-claude-code"
    }
  }
}

With a paid key:

claude mcp add --transport http orbitwren 'https://orbitwren.cybermaxtools.com/mcp?via=use-with-claude-code' \
  --header "x-api-key: YOUR_KEY"

In .mcp.json, ${CYBERMAX_API_KEY} is read from the environment so the key is not committed.

Where it goes:

stored by the CLI: local scope (default, you in this project), project scope (.mcp.json, shared), user scope (you, every project)

Tools you get

Endpoint checked 2026-10-09: https://orbitwren.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 6 tools, all marked read-only. No key was used and no tool was called.

Tool	What it does	Required inputs
`orbital_compute_projects`	Orbital data centers and space AI compute projects (data centers in space, AI chips in orbit, FCC constellation filings): company, partners, hardware in orbit, launch date, vehicle, status, scale, publicly stated funding, NORAD IDs and source URLs. Use for questions like "who is building orbital data centers?" or "are there data centers in space?". Filter by company, status, category or text.	none
`next_compute_launch`	The next launch carrying a tracked orbital data center / space AI compute project, with NET, window, status, seconds to launch and the projects on board (null when none is scheduled).	none
`upcoming_launches`	Upcoming orbital launches from The Space Devs Launch Library 2 with rideshare and orbital-compute flags; filter by days ahead, rideshare, compute, provider, country or text.	none
`compute_satellite_orbits`	CelesTrak orbit elements with perigee/apogee and period for tracked orbital-compute satellites (by NORAD ID or project).	none
`orbital_compute_alerts`	Orbitwren Alerts: classified events for orbital data centers and space AI compute (new_project, launch, date_change, status_change) with companies and source URLs. Needs a paid Orbitwren key (Alerts plan $5/month).	none
`tracker_changes`	Day-to-day changes: project status, launch dates, NORAD IDs, tracked launch NET/status.	none

Test the endpoint from a terminal

This lists the tools without a key and without calling any of them:

curl -s https://orbitwren.cybermaxtools.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

If it does not work

If a project-scoped server does not load, Claude Code asks you to approve servers from .mcp.json the first time.
The free tier has a daily limit (see the pricing line above); a paid key raises it.
