Nasa Images

kaitoy/nasa-images-mcp-server

Connects Claude to NASA's image library API with a built-in viewer UI using the MCP Apps Pattern. Exposes two tools: search_nasa_images to query by keywords, and get_next_image to navigate results sequentially. Maintains stateful sessions so your search results persist across interactions. Supports both stdio transport for local Claude Desktop usage and HTTP with SSE for remote deployments. The viewer resource renders as HTML directly in compatible clients, letting you browse space imagery without leaving your chat. Useful when you want Claude to find and display NASA photos of missions, planets, or astronomical phenomena. Requires a free NASA API key with a 1000 requests per hour limit for registered users.
