SpaceNexus space data

Official14 tools

by spacenexus

Read-only space industry data: launches, slips, funding, companies, space weather, Moon race, jobs.

us.spacenexus/spacenexus — MCP Server Model Context Protocol

The us.spacenexus/spacenexus MCP server provides read-only space industry data. It covers launch activity, launch slips, funding information, companies, space weather, Moon race updates, and job listings. The server’s focus is data access rather than modification.

🛠️ Key Features

Read-only space industry datasets
Launches and launch slips
Funding data
Company information
Space weather
Moon race data
Jobs listings

🚀 Use Cases

Querying space launch timelines and slip information
Looking up funding and company records in the space sector
Checking space weather-related data
Tracking Moon race developments
Finding job listings tied to the industry

⚡ Developer Benefits

Structured access to multiple space-industry data categories
Suitable for read-only integrations and downstream analysis pipelines

⚠️ Limitations

No write capabilities (data is read-only)

Captured live from the server via tools/list.

next_launches

Upcoming orbital launches from the SpaceNexus manifest (the next 50 scheduled), filterable by provider, rocket, launch site and country. Each launch has its NET date and precision, status, the date changes our ledger recorded, and its page URL. realSlips and otherDateMoves count only changes our sync saw when they happened; caughtUpDateMoves counts changes it only caught up with late (made earlier, on a day we do not know), which are never counted as slips.

Parameters6

provider	string	optional	Launch provider: a name or common short name, e.g. "SpaceX", "ULA", "ISRO", "CASC", "Rocket Lab".
rocket	string	optional	Rocket, matched as a substring, e.g. "Falcon 9", "Starship", "Long March".
site	string	optional	Launch site: a spaceport name or slug ("Cape Canaveral" includes Kennedy, "vandenberg", "Starbase", "Andoya") or any pad name.
country	string	optional	Country of the launch site, by name or code, e.g. "United States", "China", "France" (Kourou), "NZL".
limit	integer	optional	How many launches to return (1 to 20).
include_recent_outcomes	boolean	optional	Also return launches flown in the last 30 days with their outcome.

launch_slips

Recent launch date changes as the SpaceNexus slip ledger recorded them (old date, new date, size of the move, kind of move), with totals since recording began and the provider scorecard once the ledger is large enough. Each change carries observation: live (our sync saw it when it happened) or catch-up (our sync only caught up late, so observedAt is when we saw it, not when it changed). Caught-up changes are returned apart in caughtUpChanges and never counted in the summary figures.

Parameters4

rocket	string	optional	Only moves of this rocket (substring).
real_moves_only	boolean	optional	Leave out placeholder moves (a "NET 2026" style date firming or rolling); keep slips, pull-ins and adjustments.
limit	integer	optional	How many recent date changes to return (1 to 25).
