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.

  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/tools/memory-tools.js:381-408 (schema)

  Tool schema definition exported from memory-tools.js (matches mcp.js version, possibly source template).

  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"]
  }
