Implementation Reference

• src/tools/clients.ts:94-112 (handler)

  The DeleteClientHandler class, which implements the ToolHandler interface, processes the request to delete a client via the Harvest API.

  class DeleteClientHandler implements ToolHandler {
    constructor(private readonly config: BaseToolConfig) {}
  
    async execute(args: Record<string, any>): Promise<CallToolResult> {
      try {
        const inputSchema = z.object({ client_id: z.number().int().positive() });
        const { client_id } = validateInput(inputSchema, args, 'delete client');
        
        logger.info('Deleting client via Harvest API', { clientId: client_id });
        await this.config.harvestClient.deleteClient(client_id);
        
        return {
          content: [{ type: 'text', text: JSON.stringify({ message: `Client ${client_id} deleted successfully` }, null, 2) }],
        };
      } catch (error) {
        return handleMCPToolError(error, 'delete_client');
      }
    }
  }

• src/tools/clients.ts:185-199 (registration)

  The registration of the 'delete_client' tool within the registerClientTools function, associating it with the DeleteClientHandler.

  {
    tool: {
      name: 'delete_client',
      description: 'Delete (archive) a client. This action archives the client rather than permanently deleting it, preserving historical project and billing data.',
      inputSchema: {
        type: 'object',
        properties: {
          client_id: { type: 'number', description: 'The ID of the client to delete' },
        },
        required: ['client_id'],
        additionalProperties: false,
      },
    },
    handler: new DeleteClientHandler(config),
  },
