Implementation Reference
- index.js:463-487 (handler)The handleRetrieve function reads a compressed file and its metadata from disk, decompresses the data using the stored algorithm, and returns the original data along with metadata.
handleRetrieve(args) { const { key } = args; if (!key) return { error: 'Missing "key" parameter' }; const dataPath = join(STORE_DIR, `${key}.bin`); const metaPath = join(STORE_DIR, `${key}.json`); if (!existsSync(dataPath) || !existsSync(metaPath)) { return { error: `Key "${key}" not found` }; } const metadata = JSON.parse(readFileSync(metaPath, 'utf-8')); const compressed = readFileSync(dataPath); const original = this.decompressData(compressed.toString('base64'), metadata.algorithm); this.stats.operations++; return { key, data: original, original_size: metadata.originalSize, compressed_size: metadata.compressedSize, algorithm: metadata.algorithm, stored_at: metadata.storedAt }; } - index.js:606-615 (schema)The tool definition and input schema for 'retrieve' in getToolDefinitions(). It declares the tool name, description, and inputSchema requiring a 'key' (string).
{ name: 'retrieve', description: 'Retrieve and decompress previously stored data by key.', inputSchema: { type: 'object', properties: { key: { type: 'string', description: 'The key used when storing the data' } }, required: ['key'] } - index.js:687-687 (registration)The 'tools/call' handler dispatches the 'retrieve' tool name to the handleRetrieve method.
case 'retrieve': result = this.handleRetrieve(args); break;
