create_working_memory
Generate a temporary working memory with a specified time-to-live, enabling AI systems to store and manage content and embeddings for short-term task continuity and context retention.

Implementation Reference
- mcp.js:656-662 (handler)MCP server tool handler for 'create_working_memory': extracts arguments and calls memoryManager.createWorkingMemory, returns JSON stringified result.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:406-434 (schema)Tool schema definition including name, description, and inputSchema for validation in ListToolsRequest response.{ name: "create_working_memory", description: "Create a temporary working memory with expiration", inputSchema: { type: "object", properties: { content: { type: "string", description: "Content of the working memory" }, embedding: { type: "array", items: { type: "number" }, description: "Vector embedding for the content" }, context: { type: "object", properties: { ttl: { type: "integer", description: "Time to live in seconds", default: 3600 } }, default: {} } }, required: ["content", "embedding"] }
- src/memory-manager.js:442-460 (helper)Core implementation: creates a working memory record in the database with content, embedding, and computed expiry 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; }
