NASA MCP Server
NASA MCP server enabling AI agents to access NASA's public data APIs — retrieving the Astronomy Picture of the Day, querying exoplanet archives, accessing Mars rover imagery and weather data, searching the NASA image library, and integrating NASA's scientific datasets into agent-driven astronomy and space research workflows.

🔒 Security
HTTPS. Free API key. Public data. Community MCP. No sensitive data.
⚡ Reliability
Best When
An agent needs access to NASA's rich collection of public space data — astronomy images, exoplanet data, Mars mission data, and more — for research, education, or content creation.
Avoid When
You need commercial space data, satellite tracking, or real-time astronomical data beyond NASA's APIs.
Use Cases
- • Retrieving NASA Astronomy Picture of the Day from educational agents
- • Querying exoplanet data from astronomy research agents
- • Accessing Mars rover photos and weather from space exploration agents
- • Searching NASA's image and video library from media agents
- • Getting Earth observation data from environmental analysis agents
- • Enriching astronomy content with NASA data from content creation agents
Not For
- • Real-time satellite tracking (use dedicated tracking APIs)
- • Commercial space data beyond what NASA offers publicly
- • High-resolution uncompressed imagery (large file downloads)
Interface
Authentication
NASA API key optional but recommended. Free API key from api.nasa.gov increases rate limits. DEMO_KEY available without registration at lower limits.
Pricing
NASA APIs are completely free public APIs. MCP is free community project. No costs.

Known Gotchas
- ⚠ DEMO_KEY rate limit (30/hour) is very restrictive — register for free API key
- ⚠ Some NASA APIs have higher latency — APOD and imagery can be slow
- ⚠ Image/media data may be large — handle download sizes appropriately
- ⚠ Community MCP — NASA has multiple distinct APIs with different schemas
- ⚠ Not all NASA APIs covered — check which are supported
- ⚠ Exoplanet archive queries can return large datasets
