Implementation Reference
- src/memory-manager.js:442-460 (handler)Core implementation of createWorkingMemory: inserts a new working memory record into the database with computed expiration time based on TTL.
async createWorkingMemory(content, embedding, context = {}) { try { const ttl = context.ttl || 3600; // Default 1 hour const expirationTime = new Date(Date.now() + ttl * 1000); const [workingMemory] = await this.db .insert(schema.workingMemory) .values({ content, embedding: embedding, expiry: expirationTime }) .returning(); return workingMemory; } catch (error) { console.error('Error creating working memory:', error); throw error; } - mcp.js:656-662 (handler)MCP CallToolRequestSchema handler for 'create_working_memory': extracts arguments and delegates to memoryManager.createWorkingMemory, returns JSON response.
case "create_working_memory": const workingMemory = await memoryManager.createWorkingMemory( args.content, args.embedding, args.context || {} ); return { content: [{ type: "text", text: JSON.stringify(workingMemory, null, 2) }] }; - mcp.js:407-434 (schema)Input schema and tool metadata definition returned by ListToolsRequestSchema handler.
