Implementation Reference
- src/handlers/nasa/osdr_files.ts:18-70 (handler)The osdrFilesHandler function implements the core logic for the 'nasa_osdr_files' tool. It validates the accession_number parameter, fetches data files metadata from the NASA OSDR API, adds the result as a MCP resource, and returns formatted JSON content or error.export async function osdrFilesHandler(args: OsdrFilesParams) { try { // Validate required parameters if (!args.accession_number) { throw new Error('Missing required parameter: accession_number must be provided.'); } // Base URL for the OSDR API const baseUrl = 'https://osdr.nasa.gov/osdr/data/osd/files'; const apiUrl = `${baseUrl}/${encodeURIComponent(args.accession_number)}`; // Make the API request using GET const response = await axios.get(apiUrl, { // OSDR API might require specific headers, e.g., Accept headers: { 'Accept': 'application/json' } }); const data = response.data; // Create a resource URI const resourceUri = `nasa://osdr/files/${encodeURIComponent(args.accession_number)}`; const resourceName = `OSDR Files for ${args.accession_number}`; // Add response to resources addResource(resourceUri, { name: resourceName, mimeType: "application/json", text: JSON.stringify(data, null, 2) }); // Format the response for MCP return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] }; } catch (error: any) { let errorMessage = `Error accessing NASA OSDR Files API: ${error.message}`; if (error.response) { // Include more detail from the API response if available errorMessage += `\nStatus: ${error.response.status}\nData: ${JSON.stringify(error.response.data)}`; } return { content: [{ type: "text", text: errorMessage }], isError: true }; } }
