"Supabase (open source Firebase alternative)" matching MCP servers:

Provides real-time International Space Station position and the list of people currently in space via the Open Notify API.

Provides AI assistants with live information about who is currently in space and the location of the ISS, using the free Open Notify API.

A local, open-source MCP server that wraps astronomy data services (SIMBAD, JPL Horizons, VizieR, etc.) behind a conversational interface, enabling AI assistants to answer astronomy questions with real, typed, and provenance-tracked data.

Enables MCP clients to retrieve live worldwide launch schedules with countdowns, Starship status, satellite and ISS pass predictions for any location, and visible Starlink train forecasts, with cited source URLs and fetch timestamps.

Read-only MCP server that enables astronomy session planning against the Telescopius REST API, covering target search and info, twilight and rise/set times, nightly weather forecasts, event calendars, news, observing lists and equipment. It can also open the Telescope Simulator in a headed browser to capture framing screenshots for a given rig or mosaic layout.

Full-spectrum GEOINT server with 171 tools covering satellite imagery, aircraft tracking, maritime surveillance, military intelligence, conflict monitoring, environmental analysis, critical infrastructure, sanctions compliance, and cyber-geo intelligence from open-source data.

Enables any MCP client to plan and run verifiable analysis of engine hot-fire and bench test data through tools that open runs, segment phases, check sensor health, redlines, valve response and oscillations, compare simulations, verify every reported number against an evidence ledger, and write HTML reports. All findings stay traceable and reproducible from deterministic tool calls rather than raw samples.

Enables querying the ESA Gaia star catalogue (DR3) for astrometric and photometric data via cone searches, source ID lookups, and arbitrary ADQL queries over the TAP service.

Provides access to NASA's open APIs including astronomy imagery, Mars rover photos, asteroid tracking, Earth observations, and media library through natural language interaction.
