Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| NASA_API_KEY | No | Optional API key for NASA APIs. Without it, DEMO_KEY is used with lower rate limits. | DEMO_KEY |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| apod_por_fechaA | Trae la Astronomy Picture of the Day (APOD) de la NASA para una fecha. Si no pasás fecha, usa hoy. Úsala cuando el usuario pida la imagen astronómica del día, APOD o una foto del cosmos de cierta fecha. |
| fotos_marteA | Trae fotos de los rovers de Marte (Curiosity, Opportunity, Spirit, Perseverance). Podés filtrar por sol, fecha terrestre o cámara. Si no pasás sol/fecha, devuelve las más recientes. Úsala cuando pidan fotos de Marte o de un rover. |
| asteroides_cercanosA | Lista asteroides cercanos a la Tierra (NeoWs) en un rango de fechas de hasta 7 días. Ordena por cercanía. Úsala para acercamientos, NEOs o si hay algún asteroide relevante. |
| imagen_tierraA | Trae imágenes de la Tierra completa vistas desde el satélite DSCOVR (EPIC) para una fecha. Si no pasás fecha, usa las más recientes disponibles. Úsala cuando pidan ver la Tierra desde el espacio o fotos EPIC. |

Scored across 4 tools
Each tool targets a distinctly different NASA resource: APOD, Mars rover photos, near-Earth asteroids, and Earth imagery. There is no overlap in purpose or data source, making selection unambiguous.
All tool names follow the same pattern: lowercase, underscore-separated, noun_phrase (apod_por_fecha, fotos_marte, asteroides_cercanos, imagen_tierra). Although not verb_noun, the naming is highly consistent and predictable.
Four tools is slightly on the small side for a 'cosmos' server, but each tool covers a major astronomy data source. The count feels reasonable for a focused NASA data provider, though a few more tools could enrich the set.
The server covers four key read-only astronomy features (APOD, Mars photos, asteroids, Earth imagery). It lacks other common NASA APIs (e.g., exoplanet data, solar activity), but the included tools provide a coherent and functional surface for common space-related queries.
