Tools

Tool	What it does	Effect	Inputs (* required)
`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.	read-only, calls public sources on the internet, never destructive	`company`, `status`, `category`, `q`, `inOrbit`, `limit`
`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).	read-only, calls public sources on the internet, never destructive	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.	read-only, calls public sources on the internet, never destructive	`days`, `rideshare`, `compute`, `provider`, `country`, `q`, `limit`
`compute_satellite_orbits`	CelesTrak orbit elements with perigee/apogee and period for tracked orbital-compute satellites (by NORAD ID or project).	read-only, calls public sources on the internet, never destructive	`norad`, `project`
`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).	read-only, calls public sources on the internet, never destructive	`since`, `type`, `company`, `limit`
`tracker_changes`	Day-to-day changes: project status, launch dates, NORAD IDs, tracked launch NET/status.	read-only, calls public sources on the internet, never destructive	`since`, `limit`

Security and data handling

Your tool arguments are used only to answer that call. They are not saved to a database, shared, sold or used for training.
To make repeat lookups fast, some servers keep the public answer to a lookup in Cloudflare's edge cache for up to 7 days (most for 1 hour or less). It holds the public result, not who asked.
Free tier: a per-day counter keyed by a SHA-256 hash of your IP address and the date (in a Cloudflare Durable Object). The raw IP is not stored.
Paid key: the key is checked with the payment provider (Stripe; Polar for older keys) and the result is cached for 10 minutes; usage is counted per key per month.
No accounts, cookies or tracking on the MCP endpoint. Errors may appear in Cloudflare's short-lived Worker logs.
Every tool is read-only: it looks up public data and returns it. No tool writes, deletes, sends messages or spends money.
