Spacex Overview

The spacex MCP server exposes SpaceX API v4 data and public Starlink catalog data through MCP tools. It provides launch history and schedules, rocket specifications, Crew Dragon astronaut records, and current orbital-element data for Starlink satellites. Use the hosted gateway for HTTP or streamable MCP access, or run the package locally over stdio. It fits agents that need factual SpaceX data without authentication.

Primary Use Cases for Spacex:
  • Check the latest SpaceX launch and related media
  • Compare SpaceX rocket configurations and success rates
  • Track upcoming and recent launch activity
  • Review Crew Dragon astronaut assignments
