Implementation Reference

• src/tools/memory/updateMemory.ts:28-55 (handler)

  The main handler function that performs the update_memory tool logic: checks if memory exists, appends or replaces value using MemoryManager, returns success/error message.

  export async function updateMemory(args: { key: string; value: string; append?: boolean }): Promise<ToolResult> {
    const { key: updateKey, value: updateValue, append = false } = args;
  
    try {
      const mm = MemoryManager.getInstance();
      const existingMemory = mm.recall(updateKey);
  
      if (existingMemory) {
        const newValue = append ? existingMemory.value + ' ' + updateValue : updateValue;
        mm.update(updateKey, newValue);
  
        return {
          content: [{
            type: 'text',
            text: `✓ ${append ? 'Appended to' : 'Updated'} memory: "${updateKey}"`
          }]
        };
      } else {
        return {
          content: [{ type: 'text', text: `✗ Memory not found: "${updateKey}". Use save_memory to create new memory.` }]
        };
      }
    } catch (error) {
      return {
        content: [{ type: 'text', text: `✗ Error: ${error instanceof Error ? error.message : 'Unknown error'}` }]
      };
    }
  }

• src/tools/memory/updateMemory.ts:6-26 (schema)

  Input schema and metadata definition for the update_memory tool.

  export const updateMemoryDefinition: ToolDefinition = {
    name: 'update_memory',
    description: '수정해|업데이트|바꿔|update|change|modify|edit - Update existing memory',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: 'Memory key to update' },
        value: { type: 'string', description: 'New value' },
        append: { type: 'boolean', description: 'Append to existing value' }
      },
      required: ['key', 'value']
    },
    annotations: {
      title: 'Update Memory',
      audience: ['user', 'assistant'],
      readOnlyHint: false,
      destructiveHint: false,
      idempotentHint: true,
      openWorldHint: false
    }
  };

• src/index.ts:93-99 (registration)

  Registration of updateMemoryDefinition in the tools array used for ListToolsRequest.

  // Memory Management - Basic (6)
  saveMemoryDefinition,
  recallMemoryDefinition,
  updateMemoryDefinition,
  deleteMemoryDefinition,
  listMemoriesDefinition,
  prioritizeMemoryDefinition,

• src/index.ts:160-166 (registration)

  Registration of updateMemory handler in the toolHandlers object for dynamic dispatch during CallToolRequest.

  // Memory - Basic
  'save_memory': saveMemory,
  'recall_memory': recallMemory,
  'update_memory': updateMemory,
  'delete_memory': deleteMemory,
  'list_memories': listMemories,
  'prioritize_memory': prioritizeMemory,

• src/index.ts:46-46 (registration)

  Import statement bringing in the tool definition and handler from the implementation file.

  import { updateMemoryDefinition, updateMemory } from './tools/memory/updateMemory.js';
