"SearXNG - Open Source Metasearch Engine" 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.

Model Context Protocol server for pyCycle/OpenMDAO engine-cycle workflows, enabling lifecycle management, variable inspection, execution, sweeps, and integration with CPACS aircraft analysis pipelines.

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.

Viznoir empowers AI agents to directly analyze and visualize complex 3D scientific and engineering data in cinematic resolution using a fully headless VTK engine. It enables LLMs to seamlessly execute advanced physical analysis, 3D rendering, and generate publication-ready animations purely through natural language commands.

Enables AI assistants to search and match spacecraft components by engineering requirements, retrieve full datasheet specifications, and compute mass and power budgets with traceable source citations.

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

Provides the JSBSim flight-dynamics engine as an MCP service, enabling AI agents to control and simulate aircraft in real-time through natural language.
