Logging System

The server includes comprehensive logging:

• Operation status and progress
• Performance metrics
• Rate limit tracking
• Error conditions
• Request validation

Example log messages:

[INFO] NASA MCP Server initialized successfully
[INFO] Processing APOD request for date: 2023-01-01
[INFO] Fetching Mars Rover data for Curiosity, sol 1000
[WARNING] Rate limit threshold reached (80%)

Security Considerations

This MCP server implements security best practices following the Model Context Protocol specifications:

• Input validation and sanitization using Zod schemas
• No execution of arbitrary code
• Protection against command injection
• Proper error handling to prevent information leakage
• Rate limiting and timeout controls for API requests
• No persistent state that could be exploited across sessions

Testing with MCP Inspector

The NASA MCP Server includes a script to help you test the APIs using the MCP Inspector:

# Run the provided test script
./scripts/test-with-inspector.sh

This will:

1. Build the project to ensure the latest changes are included
2. Start the MCP Inspector with the NASA MCP server running
3. Allow you to interactively test all the NASA APIs

Example Test Requests

The repository includes example test requests for each API that you can copy and paste into the MCP Inspector:

# View the example test requests
cat docs/inspector-test-examples.md

For detailed examples, see the Inspector Test Examples document.

MCP Client Usage

This server follows the official Model Context Protocol. Here's an example of how to use it with the MCP SDK:

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { HttpClientTransport } from "@modelcontextprotocol/sdk/client/http.js";

const transport = new HttpClientTransport({
  url: "http://localhost:3000",
});

const client = new Client({
  name: "mcp-client",
  version: "1.0.0",
});

await client.connect(transport);

// Example: Get today's Astronomy Picture of the Day
const apodResult = await client.request({
  method: "nasa/apod", 
  params: {}
});
console.log(apodResult.result);

// Example: Get Mars Rover photos
const marsRoverResult = await client.request({
  method: "nasa/mars-rover",
  params: { rover: "curiosity", sol: 1000 }
});
console.log(marsRoverResult.result);

// Example: Search for Near Earth Objects
const neoResults = await client.request({
  method: "nasa/neo",
  params: {
    start_date: '2023-01-01',
    end_date: '2023-01-07'
  }
});
console.log(neoResults.result);

// Example: Get satellite imagery from GIBS
const satelliteImage = await client.request({
  method: "nasa/gibs",
  params: {
    layer: 'MODIS_Terra_CorrectedReflectance_TrueColor',
    date: '2023-01-01'
  }
});
console.log(satelliteImage.result);

// Example: Use the new POWER API
const powerData = await client.request({
  method: "nasa/power",
  params: {
    parameters: "T2M,PRECTOTCORR,WS10M",
    community: "re",
    latitude: 40.7128,
    longitude: -74.0060,
    start: "20220101",
    end: "20220107"
  }
});
console.log(powerData.result);
