Implementation Reference

• src/tools/memory/deleteMemory.ts:22-43 (handler)

  Main handler function for delete_memory tool. Uses MemoryManager to delete the specified memory key and returns a ToolResult with appropriate success or failure message.

  export async function deleteMemory(args: { key: string }): Promise<ToolResult> {
    const { key: deleteKey } = args;
  
    try {
      const mm = MemoryManager.getInstance();
      const deleted = mm.delete(deleteKey);
  
      if (deleted) {
        return {
          content: [{ type: 'text', text: `✓ Deleted memory: "${deleteKey}"` }]
        };
      } else {
        return {
          content: [{ type: 'text', text: `✗ Memory not found: "${deleteKey}"` }]
        };
      }
    } catch (error) {
      return {
        content: [{ type: 'text', text: `✗ Error: ${error instanceof Error ? error.message : 'Unknown error'}` }]
      };
    }
  }

• src/tools/memory/deleteMemory.ts:6-20 (schema)

  ToolDefinition object defining the schema for the delete_memory tool, including input schema requiring a 'key' string parameter.

  export const deleteMemoryDefinition: ToolDefinition = {
    name: 'delete_memory',
    description: 'forget|delete|remove|erase - Delete specific memory',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: 'Memory key to delete' }
      },
      required: ['key']
    },
    annotations: {
      title: 'Delete Memory',
      audience: ['user', 'assistant']
    }
  };

• src/index.ts:124-135 (registration)

  Registration of deleteMemoryDefinition in the main tools array, which is served via the ListTools MCP handler with pagination support.

  // Memory Management Tools
  saveMemoryDefinition,
  recallMemoryDefinition,
  listMemoriesDefinition,
  deleteMemoryDefinition,
  searchMemoriesDefinition,
  updateMemoryDefinition,
  autoSaveContextDefinition,
  restoreSessionContextDefinition,
  prioritizeMemoryDefinition,
  startSessionDefinition,

• src/index.ts:642-643 (registration)

  Dispatch registration in the central tool switch statement within executeToolCall, mapping 'delete_memory' calls to the deleteMemory handler.

  case 'delete_memory':
    return await deleteMemory(args as any) as CallToolResult;
