Connect NASA to LangGraph

Run KosmoKrator integration calls from LangGraph nodes while preserving local credentials and permissions.

Use a graph node that calls the KosmoKrator CLI for deterministic steps or an MCP client for dynamic tool selection. The gateway is local, scoped to this integration, and starts with --write=deny so LangGraph can inspect read-capable tools without receiving write access by default.

NASA MCP Config for LangGraph

Headless CLI calls fit repeatable graph edges; MCP fits exploratory agent nodes.

Why Use KosmoKrator Here

Scoped tools

Expose only NASA instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.

NASA Tools Visible to LangGraph

LangGraph sees stable MCP tool names generated from the NASA integration catalog.

MCP toolSource functionTypeDescription
integration__nasa__nasa_get_apod nasa.nasa_get_apod Read Get the NASA Astronomy Picture of the Day (APOD). Returns the daily astronomical image or photo along with an explanation written by a professional astronomer. You can request a specific date or a range of dates.
integration__nasa__nasa_get_asteroid nasa.nasa_get_asteroid Read Get detailed information about a specific Near Earth Object (asteroid) by its NASA ID. Returns orbital data, estimated diameter, close approach history, and hazard assessment.
integration__nasa__nasa_get_asteroids nasa.nasa_get_asteroids Read Get Near Earth Objects (asteroids) for a date range from NASA. Returns a list of asteroids with their estimated diameter, velocity, distance from Earth, and whether they are potentially hazardous.
integration__nasa__nasa_get_current_user nasa.nasa_get_current_user Read Get information about the current NASA API configuration. The NASA API is public and does not require user authentication — this tool returns the API key status and available endpoints.
integration__nasa__nasa_get_mars_rover_photos nasa.nasa_get_mars_rover_photos Read Get photos from NASA Mars rovers (Curiosity, Opportunity, Spirit, Perseverance). Query by sol (Martian day) or Earth date, and optionally filter by camera. Returns photo URLs and metadata.
integration__nasa__nasa_search_images nasa.nasa_search_images Read Search the NASA Image and Video Library for space, astronomy, and mission imagery. Returns image URLs, titles, descriptions, and metadata from NASA's vast collection.
